Query: Far better than a TI...

Simply put the Casio 9850GB Plus is the best performace over price value out there. Though many schools have TI centric curriculum, I've found I have an even easier time than the TI owning students because of the Casio's straightforward interface. I highly recommend this calculater, it's easy to use, as fast (or faster in my expierence) in graphing sine functions when compared to TI's, and the price is unbeliveable (I got mine for $49). My advice, go against the crowd, get a Casio. You'll thank me later.
