any cheap TI 83+ online?
after many years of using casio calculators (8 years now) I think I will have to buy a TI so that I can stay up in my AP chemistry class, since I don't have time to figure out how to do it on my calculator. Now, the big Q. Does anybody know of a good place to get TI's for cheap prices? preferably under 90 bucks, I don't care if it's used, but I also don't really want to get it off ebay. thanks
