IMO 'gaming' mouses and keyboards are completely overrated and blown out of proportion. Its a matter of getting comfortable with whatever you use. It seems all too much that 'gaming' mouses/keyboard just equates to the bling factor...... ie LED lights, display readouts, fancy artwork......etc.

This is a pretty good article and worth a read if you havnt seen it already: http://www.esreality.com/?a=longpost&id=1265679&page=21. Doesn't cover the latest and greatest newer mice, but very useful. Find the sensitivity settings which you are comfortable with, and get a good mousing surface.

Personally I use an MX310 + Ultra-X keyboard combo I got from ZZF for $15 shipped. With the USB polling rate patch, its among the best 'gaming' mice on the market out there. Doesn't look as pretty though, but hey - gets the job done, cheaply, and damn well if I may say so.....
