Yeah, some of the very early models are quite expensive, but if you stick to the calculators (i.e. not "pocket computers"), then most of the models released after the mid-1980s are very affordable. I think I paid around $30-40 each for the fx-4000P and fc-200, $10 for a new-in-box fx-6300G, and about $15 for a lovely fx-9700GE (top of the line as far as the 1st-gen array-memory models go). I've also picked up a few other assorted models for prices somewhere in that spread. The old CFX 3-color-LCD models are comparably priced.

I've purchased very few HPs for less than those prices, and the ones I did were generaly either parts machines/fixer-uppers, or horrible, like the 9g.
