Well I really like 3M's mousing surface and still recommend it to alot of people. Especially if you're still in school because it doesn't take up any desk space and you don't get things jammed/caught on it when pushing things around the desk. I recently changed to a $16 cloth mouse pad with gell wrist rest, since I play games online for hours on end (mainly D2) my wrist was starting to get sore so I had to switch.
