The best trackball mouse I ever used was made by logitech, late 90's - 01. Large ball, same size as std kensington, 4 button. Out of the blue they quit making, grumble, grumble... the ball was in a housing accessed from both sides, not the top, thumb, middle finger on the sides. It was the most ergonomic trackball I've ever used. It was great for gaming also, fingers, wrist never got tired even after hours.
Edit: I found photo's of the logitech trackman marble fx... was so bummed when they quit making it. Looking back the 3 buttons next to my thumb was also a great feature.
Also, was looking at some of the new trackballs on amerzit tonight. Several of them are 8 button, interesting.
