Try the Razer Diamondback, havent any of you heard bout these guys, specialized "lazer" mice for gaming purposes. The diamondback is their newest model, it is the best mouse ive seen. www.razerzone.com
One thing, they are a bit pricey but well!!! worth it, my friend has one, and uses if for Day of Defeat, and C.S. its rocks, the diamondback has 2x the viewing as regular mice, it can see a lot.
