Hey again- I went to Tekserve here in Manhattan, and I was very let down that the geeks there couldn't tell me which mouse would work. Here's the question: I will be running Maya, and my teacher told me to get a 3-button mouse. When I went to the place, they could not clarify for me if the 2-button ones with the scroll wheel would work as a 3. My guess was "no," so I didn't buy one. Can someone lemme know which mouse I need to get? The more compact, the better! Also- the cheaper the better!! Thanks, guys!
