 I am glad I purchased this 2nd hand calculator! May 11, 2010
Tom (CA, USA)
I bought the calculator from Abacus via Amazon.com. In 2-3 days, I received the calculator even though it came with the standard free mailing option. The calculator is in a really condition. It works well. The batteries of the calculator were also new. I am glad that I purchased this 2nd hand calculator instead of paying much more for a new one!

This was truly a life saver for me; at the last minute my instructor states that we needed this calulator in order to past the course. The time frame it took to reach me was outstanding; was very pleased!
 A complete friggin joke. April 26, 2010

Negative 5 stars. Lets be real people, the mere existence of this device is perturbing. It is the one electronic that has evolved absolutely none in 15 years and gone UP in price!! My friend bought one recently in a pinch, he thought it might help him with calculus. I figured it'd have some new chip technology and would graph at a reasonable rate. Both no. So then I downloaded a FREE graphing calculator app on my outdated Android phone. And it's friggin marvelous: instantaneous, intuitive, will do a 3d graph of x=sin(y) (3x faster than the ti does sin(x)) that rotates in full color with ability to pan and zoom on the touchscreen.
I can't even list all the advantages of an android/iPod over the TI's in this space, but what about battery, USB, internet, brightness, 192mb ram.. The TI-83 must be $3 to make by now with it's laughable 32kb!! of ram and 6 mhz processor. This makes my (dated!) phone exactly 88 times as fast with 6000 times the memory. I did that calculation on my phone and if I threw in a sin(x) at the end it would have automatically graphed 88sin(x) for sh!ts and giggles. Then I could zoom out 10 times, take a screenshot, and email it to you, just because I can (in 30 seconds). Hello! Note that even if I didn't opt for a cell plan I could still use wifi. Ahem. Wifi.
Shame on the people who keep this piece of junk in the school systems as a standard. Realistically, a dedicated device of this price today could be phenomenal. Apple should make one. TI is going to (and deserves to) be brutally trounced in the calculator market for this eventually, but in the mean time they're basically restricting learning in schools to be done at a snails pace with minute functionality for a large profit, and for the massive portion bought by the school system, at your expense.

The shipping time was not too long and the calculator works as it was said to. It is used and has some marks and scratches, but I do not mind, it does the job.
