For my Arthur in the hand I find the Thumb Ball Logitec mouse very good.

Then, I also now find the Logitec MX Laser, with all those extra buttons built in--also very good.

I tend to swap between the two depending on the type of work I am doing and it's particular effects at the time on old Arthur!
