TI-81 CAlculator! EXCELLENT!Review created: 03/01/07

Buyers are stupid! They think because these are old they are not worth anything so the prices on ebay stay very low! How silly the buyers with their stupid mental understanding are on old items. If you went to buy a calculator that did not even graph you would pay at least $40 in a store for a sientific calculator that doesn't even graph! So to all the dummies who think these are not worth bidding up past $8 on ebay auctions because of their age, go ahead and buy a stripped model for $50, be my guest! I will buy this one thank you! It does 10 times more work and has 20 times more features than the ones you buy in stores that cost 4 times more money!

I bought the calculator for my daughter for a college class. A used one was much cheaper than a new one, and I knew she would probably not need to use it again after the class. The seller had a 100% positive rating and stated that the calculator worked fine. It does work fine and saved me a lot of money.

Excellent Calculator. I bought this calculator to use on the ACT and it worked great. This calculator is great.
However, if you need to do more advanced calculations, I recommend that you find another calculator. It works well for the simple stuff, but won't perform ln regressions and other more advanced calculations.
All in all, this calculator is very good for what I needed it for.

TI-81 Graphic Calculator ManualThe manual was in good condition and was what was needed and ask for. The price was excellent. It was much better than trying to print out the down-loaded version of the same. It was speedily sent.
