I'm wary of going with wireless on anything more critical than headphones. With my luck, the batteries would die right in the middle of an important project. Anyway, I have been quite pleased with my MS Wheelmouse Optical (basically a budget version of the Intellimouse, AFAIK). Logitech mice may be good (can't comment there, since I haven't experienced one), but I'd suggest, unless you don't care about the weight and battery life, to stick with either a MS or Logitech corded optical mouse.
