Re: Different Calculators -TI's
The TI83 series is pretty much the same, be it plus, silver etc... Theres some difference between memory and the connectivity with PCs and other TI units. If you want to import stuff, like FFT calculator and all, your easiest choice would be the TI83Silver, which has a USB connectivity kit. The TI83 is different from TI89 (or ti92 or voyager) as the latter is more of an engineering tool with vectors, so you really dont want to go for the TI89. They are fairly to use with a wealth of online resources and tutorials, even the book that comes with it is pretty convenient.
