I use the diamond back to, it has great precision and the buttons are great, the only negative I can think of is that it is a bit too small, but anyways it is a good mouse
i use an atomatic razor no i use a blue tooth mouse and a key bord, the mouse is 4 buton and a scroolweel boton and left and right scrollweel steer(i duno how to explail lol)
I have heard some great things about razor mice, although I would recommend checking out logitech's offerings as well to see if they fit your hand better (it does for me).
