Just registered to let you know:
Roccat has this new mouse, its ambidextrous and you can switch out the side panels, they ship with several different ones but the neat thing is, you get the 3d printing software shipped too and so you can pretty much design your own side panels , print them out and stick them on your mouse. They also provide a 3d library, where you can just copy designs from other users and print those out
