Cheap RPN calculator

[Les Bell]

Pfft! Who doesn't need scientific functions?

Picking up a cheap RPN (scientific) calculator via eBay is just a matter of patience and a little tactics. I'm by no means a serious collector, but I've won an HP-11C for just under $30, an HP-45 for just a little more, and a nice HP-25 for just a bit more again.

Around the hundred-dollar mark, I got a 32SII in perfect condition, and $20 more brought a new manual. I still reckon a sensibly-priced 11C is the best bang for the buck, though.

If you don't need a calculator urgently, then relax and just enjoy the fun of snaring a bargain.
