FOUND: Texas Instruments 83 (or 83+ or 84) graphing calculators
#5
Since they're still in use at most high schools these days, $20 - $30 is really a donation. What I've seen around here, is that most are passed down, and around among siblings, family friends, club/sports teammates, etc., on a very local level. We (or more accurately, Baby Buzz) at one time had three slightly different models accrued during his HS career. Prior to going off to college, he passed down his two least favorite models to other students, and kept, and used the one he liked best while at college. He's even used the keeper several times since joining the post-college "real world".

Why don't your adult students either just buy a $50 - $60 one that you note, and keep it for the long haul, or resell it after their classes are over, and likely recoup their investment? Why is your responsibility as an educator to provide a stable of lendable calculators?

I'm not sure how the "sharing circles" work in your school area, but from what I've seen around here, over 50% of the calculators are recycled among the student population each year; we don't see much local CL/ebay action, and the couple that do show up cheaply from time to time, I would bet are either stolen, or found ones that didn't have identification. Try to endear yourself into your local sharing circles, as that may prove fruitful.
Good luck.
