Logitech used to make the best cheap gaming mouse in the business. The Logitech MX518 was the under $US100 ($132) dream machine everyone recommended to new gamers. Whether you spent 12 hours a day in World of Warcraft or were constantly fragging infants in Counterstrike, the MX518 was a workhorse mouse with the best sensor available and just enough extra buttons to let you get stuff done.
