On my PC I use an old 3-button Logitech corded mouse, non-optical. It's done just fine for me for years (but then, I don't game much, or don't do things that require the mouse a lot, use the joystick instead).
When I got my first laptop I had a heck of a time using the touchpad, so I got a MacAlly 2 button with scrollwheel optical corded USB mouse. The big advantage was being able to use practically any surface for 'mousing.'
In terms of wireless, my parents had a wireless logitech (non-optical, RF) for a few years before it finally went bad. I gave them an old 2-button mouse of mine. They've considered optical mice now, and haven't decided on regular RF or BlueTooth. But as they're still running Win98SE, I think BlueTooth is going to be out of the question.
