Which Graphing Calculator to buy?

Also, if you plan on taking the AP Calculus test, the TI-89 is a huge advantage on the multiple choice calculator section.

i use TI 84+ Silver Edition.
However i think TI 89 is more helpful.Though at that time it was cheaper than TI 84. (seriously!) but my teacher preferred TI 83, or 84 and only taught us how to use those. that's why i hv to buy 84.

You're not serious, are you? Learning the TI-89's interface/inputs is way, way easier than anything with Mathematica.

And Maple is much easier than both.

I would recommend buying a student copy of Maple for $99 (less if your campus computer store has a deal; mine has it for $20). And for class buy yourself a decent scientific like the http://www.casio.com/products/Calculators_&_Dictionaries/Scientific_&_Financial/FX-115ES/" for $15.

If you do just have to have a graphing calculator, strongly consider getting the HP 50g instead of a TI.
