I would take a look at Corsair's mice, the M95 and M65. The M95 is designed more for MMOs with more buttons, while the M65 is made for FPS. Both are incredibly sturdy, and I'm considering getting the M65 RGB when it's out. http://www.newegg.com/Product/Product.aspx?Item=26-816-033
If anything like their keyboards, these should be very sturdy.
I like the sniper button feature.
It looks to be a fairly small mouse designed for a claw grip.
The Deathadder is bigger and can fit more into the palm of your hand.
The Logitech G402 is coming out soon as well. This mouse is supposed to have very fast tracking (500 inches per second, rather than 150 for the M65 or 200 for the Deathadder).
All these mice have DPI settings higher than you would typically use. I use 1600 DPI with the Deathadder and this works great. I saw someone raving about the G402 because of the tracking because they use 800 DPI and therefor move their hand a lot further to achieve the same movement.
