Hi. I'm getting sick of my Mighty Mouse (wired). The scroll ball keeps getting dirty, and the resolution isn't high enough for the high tracking speed I need to use it with a 30" display. I'm left handed though, so that severely limits my choices. The lefty Logitech MX 610 and the G3 both look good, but Logitech says they're Windows only. Does anyone know if they'll work on a Mac anyway? (I don't care if the stupid indicator lights on it work) Will I need USB Overdrive for them or not? Otherwise, any other non-notebook sized, symmetrical mice to suggest? Don't care if it has a cord or not. Don't care how many buttons it has. Just care about the tracking DPI and that it has a tilt scroll wheel.
