The HP-48 series calculators are still available! You can find them on ebay (where I got mine) as well as most university bookstores, and other places. Don't bother looking at Office Depot and the like, because TI has fairly well infiltrated the mainstream market.
I recently bought a new HP-48GX and it is an excellent product, and also bought an extender plugin from Chotkeh, for the EIT (FE) exam.
( http://www.chotkeh.com/index.html ) another excellent product. I will be ordering from them again in the future. Another place to check for extender cards is: ( http://www.dvtg.com ) I haven't ordered from them, but it looks like they have very good products as well.
HP has even made a newer calc. the HP-49 series, but I haven't heard any reviews on it other than it is more capable than the 48. How much more, I don't know.
