Title: Good Graphing Calculator
Review: I had used a TI-83 for Precalc, but really needed something a little more powerful for Calculus, so I bought an 86. One of my friends has an 89, but many tests that allow graphing calculators still don't allow a TI-89 because they have "algebraic manipulation" capabilities, plus the 86 is cheaper, so I went with that. I have not been disappointed. It has a much cleaner interface than the 83, and the 83's only real advantage, a strong financial and statistics package, can be downloaded to the 86 as an addon. Be warned though if you do that, the Graph Link cable (to the computer) is not cheap. It's a great calculator with a lot of good features. Those looking for more features can easily customize it by programming it, a pretty straightforward process.
