If you want to go optical but don't want to go cordless, you can also go that route though many people overlook the fact that they come both corded and cordless. I have an Intellimouse Explorer(cordless) and a Logitech optical(corded) as well as an Intellitrack Trackball, each has its advantage and disadvantage but for general gaming I prefer my Logitech, it seems to have better responsiveness than the intellimouse.
