I'm looking at buying a new one. I'd like to have a pinky button (button on the right side of the mouse), but I'll live without it. I'm looking for opinions. The Razor Naga looks nice, but seems like it might have too many buttons for just one thumb. Anyone use that? I also like the Logitech 700, which I'm leaning to because I already have the Logitech gaming pad and keyboard, so I figure the programming is the same, or similar.

Thoughts? Comments?
