I just bought a new model of the Logitech G5 and it seems to suck shit. It's nothing compared to my old model of the G5. I might take it back and get whatever's better. So the point of this post is: What's the best computer mouse in your opinion?
Logitech MX Revolution. You won't ever want to use another mouse ever (well except maybe to play games).
Not sure about comfort, but I really really want one of these: Razer | For Gamers. By Gamers.? | Gaming Hardware | Buy Online
