best mouse?

[MisterNatural]

If anyone decides on a Kensington product, I just want to mention that they have excellent customer service. After 5 years, my scroll wheel started acting up and Kensington is sending me a brand new one in the mail without asking for a receipt or anything. They just verified my serial number.

Anyone have experience with the Logitech DiNovo set? You get the MX-900 mouse, keyboard and a separate number pad. There's a bluetooth model I'm thinking of getting.
