No one going to mention the Casio CG-500? Amazon has them available (I thought they had been discontinued, but now they're back in stock). It gives you a giant color touchscreen, has built-in CAS, and is a major upgrade over the CG-50 that people have recommended. Here's a link to Amazon: Amazon.com : Casio fx-CG500 Graphing Calculator – Touchscreen with Stylus | CAS Functionality, Drag-and-Drop | Ideal for Advanced Math, Calculus & Engineering : Office Products
