Trackball Mice I Need A Trackball Mouse (preferably Wireless) What Would You Recommend?

I need a trackball mouse (preferably wireless) what would you recommend? - trackball mice

I use a laptop on his knees in the night, sitting in an armchair. I have a hard surface when you use a regular mouse, and I find the touchpad too heavy to be used for anything other than simple functions. I would like a ball mouse, and I can choose my hand.
