Logitech G7 Laser Wireless Gaming Mouse
 

"The G7 in my mind should be standard equipment for any computer user that wants to truly enjoy his/her computer with complete control, accuracy and problem free longevity you want for your money. Kudos to Logitech with their quick swap battery technology. Finally a wireless mouse that isn't heavy to use."
