I have found that the key is not the mouse, but the mouse pad. I have a pad that has one of the gel wristrests at the back and that makes all the difference in the world. Any time I use any mouse at another computer without the wristrest, I start having problems, so it's definitely not the mouse for me. I use the mouse from the keyboard tray as well with the pad, having the mouse too high can also be a problem.

For the record, I use a Microsoft Optical Wireless Mouse 2.0, which I love for it's lack of constraining wire, but like I said, try the gel wristrest first. If you don't use one, using it should help immensely. Then search for a better mouse if you need one.
