Great Calculator at Great Price!
I love this calculator. I do private tutoring professionally and this calculator makes my life way easier. It has all the main functions you need as well as doing limits, derivatives, and integrals as a function! I got it at discount during the back to school time at Target. Target has cheapest price even at regular price.

Great Price
My daughter needs this calculator for the last few weeks of calculus and will need it for statistics. We already have an expensive graphing calculator that was bought during high school, but needed this one for her last year of college. It was the best price we could find online or at other local stores. We also received 15% off during a sale and only paid $115.50 including tax. The only problem I had with it was that the Duracell batteries that were in the package with it were all corroded. Luckily the corrosion had not leaked onto the calculator itself or the manual, otherwise I would have exchanged it.

Great Calculator!
It does lots of stuff that other calculators in the same class could not. I love the solver, factoring, and variable based derivative and integral functions.

Ti89
The ti 89 titanium is amazing. It is well worth the money. It is a great calculator for the upper math classes but I do not recommend it for high schooler's unless their teacher requests it. It is complicated getting used to it at first but after you get use to it it is cool.

Great Calc
I have heard a common complaint of that the second and alpha words are hard to read on the metallic "titanium" color keyboard. I decided to buy one to check it out myself. The silver Alpha and yellow Diamond words are very bright and stand out, and the blue 2nd is completely readable unless in very poor lighting. Compared to the TI-84 Silver, the TI-89 Ti's Diamond and Alpha stand out way more than the green alpha of the TI-84 Silver, though the blue alpha is about the same. The screen is great, not tilted like some of the old TI-89's had it.
