Recommend me a new mouse!

My mightly mouse has finally lost its 3 button functions, and it's looking worse for wear considerably (it's been stripped and rebuilt many times!)

I've just got a new macbook pro and fancy a new one, but don't really like the magic mouse. I'm also tempted to go back to usb as the bluetooth ones are really heavy which isn't great for photoshop/cad (although open to wireless suggestions too!

Any suggestions?

Thanks!

I have an M705 (Logitech) that I like. Works very well for a middle of the road mouse.

Logitech Marathon mouse is pretty stellar!

+1 for the Logitech. Even the inexpensive ones work better than the MM.
