Okay, so I need to decide on a good, price-function (has sufficient functions) graphing calculator sometime this month and my parents say that once I get it, there won't be a next time - which probably means it has to last me the next 3 years of high school math (most likely Algebra 2 Honors, Trig/Pre-Calc Honors, AP Calculus), through college, and optimally allowed on the SAT or tests similar to it. The graphing calculator would preferably be easy to use and utilize the most out of its battery life/(solar?).
So I've come up with a few of Texas Instruments' graphing calculator: TI-84 PLUS Silver Edition, TI-Nspire with Clickpad, TI-Nspire with Touchpad, TI-Nspire CAS with Clickpad, and TI-Nspire CAS with Touchpad. However, I am open to suggestions.
