I purchased a Mad Catz M.O.U.S.9 and frankly, it's pretty terrible. I wanted a blue tooth mouse with more than the standard two buttons and scroll wheel for gaming and photoshop, but there doesn't appear to be a lot out there. I have a wired Naga for my desktop and even looked at the Naga Epic, but the wireless connector is apparently the charging station and I don't want to carry that around. I'd even settle for one I had to use a dongle for if it was a really good mouse, but I'd prefer to use blue tooth so I don't take up one of the two USB ports on my MBP. Anyone have suggestions to throw out there?
