Would you want to buy a mouse that has been in a hundred other hands? I think unless there is an exhibition model it is/should not be possible.

As for this mouse:
This is the best mouse I've ever had, if the frags don't fit it's definitely you! :)
Ergonomically it fits too... but I don't think much of monstrous mice and like it simple.
For FPS players I can highly recommend it, there is definitely nothing better on the market right now.
