Cheap PC Oscilloscopes - Any Recommendations?

Missionary Man asks: "I'm an electronics teacher looking for a good (but reasonably cheap) PC based oscilloscope for classroom demonstration purposes. I've done a reasonable amount of research and come up with a few contenders. Ideally I'd like something with a bandwidth of up to 40MHz and 2 channels. Does anyone have any tales to tell regarding the use of any of these scopes (or any others I haven't found or mentioned) and can recommend a suitable device?"

"Here's the list of my findings so far:

• The DS2200C from USB Instruments will do 2 channels at 12 bit resolution, but only to 200KHz.
• The PCS100 from Velleman at QKits runs to 12MHz, but only 1 channel. It has a bigger brother, the PCS500, that has 2 channels and 50MHz bandwidth, but is a lot more expensive.
• Picotech do cheaper ones, like the ADC-40/42, but these only operate in the KHz ranges.
• Link Instruments sell the DSO-2102S that runs to 60MHz with 2 channels, but it's a bit out of my price range.
• Finally, I found the bitscope which seems to be just what I'm looking for, combining a 2 channel scope and an 8 channel logic analyzer for a reasonable price.

I'm hoping to spend US$300-$400. I recognize the software is a fundamental part of the successful operation of these units and any comments regarding the bundled programs would be most helpful too!"

Picotech do cheaper ones

What does this mean?

God.... please don't remind me of them damn things.... everything I know about Developmental Genetics was learned by studing them damn things...

Only good thing that came of it, was that I realized that biologists are more cracked than IT people... I mean, really, who names genes Spetzle, or Sonic Hedgehog?
