One of my biggest regrets was passing up an offer to buy over 200 HP48 calculators back in the early 2000s. There was an independent book store across the street from a local tech school that had bought used 48s from students. There was one professor who required them for her class but she left and they could not move their inventory. They did have some black screen 48GX so I got those, but I should have picked up the whole lot.
They seem to be going for about $300 used, though considering inflation less than new. If you could have gotten a good deal, then you’d come out ahead. The price will only increase. I have a 48G and 48GX, and several others. I’d like to collect them all and build a nice display case to house them.
I have a display case in my office with mostly HP calculators. A few folks don't know what to think of it but I get bit of a kick out of their reaction. I love having them all in front of me to use and most importantly to remind me to remove the batteries.
