A question about graphing calculators

[MathGeek]

I need an advice about graphing calculators. I need to purchase one for my Math class, but I don't know which one to buy.

What is it that should think about, when choosing the right one? What features does it have? What features should it have in order to be a decent calculator? I've never had or used a graphing calculator, so every input is more than welcome :)

I've heard that Texas calculators are widely used, and I started looking for it, but then I stumbled on this site , and oh, what a surprise - they're all Texas! How the hell should I know which one to go for?! :argh:

If you have any suggestions regarding this, they'll be very much appreciated.

Hello and welcome to MHB! :D

Let's start by discussing what budget you have in mind and what kind of math program you have entered.

The TI NSpire CAS is the most powerful graphing calculator on the market that is still allowed on US standardized tests. It's pretty expensive, though. If you're not afraid of Reverse Polish Notation, I'd recommend taking a look at the HP 50g. It's what I have, and I think it's a fantastic calculator, second in power only to the one I mentioned before, and much less expensive!
