That's what I use and have been for years. $1.99 on ebay brand new. It's a ball mouse (I will argue to the grave that ball mice are better for FPS videogames) and the added friction of the rubber gives me more accurate control when playing FPSes. I, like Hal, hate the weight of wireless mice or heavy duty mice with 40 buttons on each side. The lighter the better and it's GOTTA have a ball or forget it. Something with the way I pick up the mouse during gameplay makes even the best of optical mice out of the question for me.
I do wonder about these expensive mice though. Some TF2 players swear that you have to have one to achieve the best results though I'm skeptical, especially with my hatred of optical mice and particularly wireless mice.
