RE for starters. Been using a Logitek LX8 Cordless Laser. Simple enough guess 5 button mouse. Easy enough on the hand. Nothing fancy and is cheap. Logitek Setpoint software sometimes a problem. Like now. Trying to get the buttons i customized to work in sketchup. It's usually ok though. everybody says dont load in the Logitek Software but I like using left side button for control and right for shift which gives me easy 12 choices combined with the 3 on the wheel.
