A Razer Naga MMO mouse [1] has 12 thumb buttons (and a couple of others which are rather hard to reach). They are perfect for cut, copy & paste, and other frequent macros / actions. The vendor software is crap, though, especially on a Mac. It often forgets or messes up bindings and macros and you have to reconfigure them. I really got annoyed after doing this a couple of times and switched to SteerMouse [2] which lets you do almost everything the Razer software does, but in a nice and straight forward GUI.
