From the sound of it, the other major cost is the radio-telescopes needed to pickup the weak signels. Mind you, I've heard that distributed radio arrays are getting better. It'd be a huge project though..
You know, if you take the resolving power of the center of the human eye, and the degrees of vision you have (about 180 by 120 degrees for full horizontal and vertical wrap-around, relative to your head), you find the max you need to see anywhere in that feild perfectly is about 10800 by 7200 pixels. Ah, but transient events! Fighter pilots can detect mommentary events lasting only one 250th of a second.
So, the ultimate display comes out at: 10800x7200 250Hz refresh 48-bit colour depth
This scares the shit out of me, and I'm not even in the states.
It scares me because I've listened to the whole backlog of Tales From the Afternow (free internet radio drama). In the distopian future it describes, all unregulated media and media devices are illegal, and ownership is grounds for removal of your Listeners Liecence.

Time is copyright, so you can't own a watch unless you're in a business that pays its fee. Else that's temporal piracy.
The show was a wonderful piece of entertainment when I first listened. Then I started noticing people actually DOING THIS STUFF.
Advised listening environment is near-darkness candlelight, late in the eveing, alone, with headphones. That's good old pre-DMA headphones. This is afterall, a pirate radio broadcast, in Queens English, from sometime after now...
Does not move unless pushed, steers well, has transmission, gearbox and engine (latter currently on garage floor), no seats, floor pan, or brakes. Exempt from road-tax, highly customisable. Origional A-series engine should give in the 40-45mpg range. The later A-series 1.3 should give only about 35mpg, but those are the penalties when you're crazy enough to want to do over 75mph.
I seem to recall a news report back in the Bosnia conflict, showing people who were desperate for electrical power building thier own generators from the scrap around them. A simple wooden raft tethered to a bridge, secured to that raft the rear axel from a car with paddle wheels attatched to each wheel. The drive shaft was then secured into the back of an old washing machine. Water turn wheels, wheels turn drive shaft, drive shaft turn motor inside washing machine, produce power.
You'd be better off buying an actuall generator, rather than the far less efficient moter-method, but the rest is easy enough for someone with basic woodworking skills and an old rear-wheel drive car laying around.
Well, it looks a lot better on the manufacturers website, out of the bright lights. There's still a lot of shine from the body though.
I think the problem here is that in anime, or any animated feature, things have to be made bigger than life, even in the ones with a more realistic style. Here though, they have tried to make it look exactly like it does on the screen, whereas it should have been toned down a bit. (can you imagine what concpet cars would look like if they were actually made as bright and bold as they were on the designers scetches?)
Front and rear forks are too short anyway, and the tyres aren't big enough. Draws too much attention to those hub-cover things.
Well, can't see how this is off-topic. Afterall, we're still talking about building electron microscopes.
The pump I mentioned was pretty old, and never got to more than the 10^-6 or so. It did have a LN dewar for cooling. Anyway, my best pump should be able to reach 10^-5 or 6, ona leak-free system, depending on the pumping time. Because the pumps I obtained were "damaged", I got them for free. They were actually just old and too tempremental for use on the production line. I haven't had a problem with them though.
I gotta say though, building from scavenged parts, your 100k estimate sounds WAY more than I'd say. I would have thought more half that at most.
Well, asside from making sure you use vacuum-compatible materials that won't harbor too much gas, it's not that hard to make a vacuum enclosure. I've bought lots of vacuum equipment off eBay, and scavenged old parts from places I've worked. (sitting 1 meter from a rebuilt Leybold Turbovac PT 50, and other parts)
I recall the ancient SEM at the first place I worked. 1960s equipment. I got okay images after it was cleaned up, and was only drawing vacuum through an old piston-pump. Ex-refridgeration pumps can draw better vacuum than those.
My grandfathers new microwave isn't on Google, and beleive me I've looked. He therefor has a magical place on his worktop that can superheat salmon-en-croute by no visible means.
I have to say, I allways thought if they were to make a Dwarf movie, they should enforce the level of special effects used in "Aliens". I beleive the same should be done with the HHG. Models and minimal CGI editing, but at a higher than TV quality. Both gritty and comphy.
Micro-editing, as the process is called, created a stir last year when some broadcasters were reported to be using the technology to squeeze more advertisements into the same block of time.
Hunting around, it seems the total coverage of the human gaze is about 50-60degrees. Assuming that's correct (for research purposes, I'd love to know where you found the biological stats?), then it's fair to work out that the maximum screen resolution we'd ever need is about 3600 (taking 1 arc-minute for safetys sake).
I've got a monitor with it's horizontal rez set to 1280, so three of the same screens, set side-to-side, and with my head positioned close enough that they take up my entire feild of veiw.. well, guessing a bit here, but I can't make out the individual pixels from that distance, so it'd seem you're right.
Now, taking a leap of faith, and presuming a touch-screen future, I'd guess that'd make the optimum computer interface display about 63" with a screen resolution of about 3600x2880. We're still a little way from screens that size, but consumer machines are getting quite close to those resolutions. But then, you don't need the size, if you sit closer. I'd try that, but my eyes hate me enough from a day on the computer.
Still though, seems they've exceeded the resolution requirements. Now for the frame-rate.
Hmmm.. you'd need some aluminium bar-stock, a small die-casting setup, watchmakers lathe and an ultra-clean glovebox for assembly. And of course sacrificial drives to grab the platters and heads out of. You'd need to redesign the driver board and remember to feed extra power to the motor to counter all the extra mass. And while you're at it, why not cap the whole thing off with a perspex window and internal LEDs.

Being a scavenger, I can only ask..
So, what can we use it for?
Even if it no longer has power for full transmission, there's still power enough to run basic (diagnostic?) uplinks? Perhaps minimal data traffic, or ham radio?
Best keep an eye on it anyway, it wouldn't be the first satellite to come back to life by suprise.
