@tbry23m: You can pick them up for about $40-60 on craigslist. And they’re amazing. You will use one all throughout college if you plan on doing any kind of science, math, or engineering. I use mine every bloody day. 3D graphing, solving variable functions, cross and dot products, matrices, etc. It’s pretty powerful, and it will greatly simplify your life by learning it (if you’re something like an art history major or a business major though, yeah, you just need a pencil and maybe some paint).
