In general, I find a simple Logitech optical wheel mouse (two buttons, one scroll wheel, with wire) to be the best. I used several different ADB-mouses on my Beige G3 and all of them sucked big time. I then tried mentioned Logitech mouse connected to a USB port and it was like having a new computer. Seriously: using that simple USB mouse on my Beige G3 improved it more than the Radeon 9200 and the 1 GHz G3 I upgraded it with...

Reliable, precise and a perfect fit.
