Don't get a product-sponsored mouse, their prices are always jacked up just because it's 'officially licensed'.

If you play claw-style, I highly recommend the Razer DeathAdder, it's got a nice ergonomic design that feels nice on your hands, and has no long-term strain. Even if you play palm-style, you will still be able to use this mouse with ease, only having minor difficulty using the middle-mouse click. It's a nice $60 as well.

There's also a nice shiny version that lights up blue (no extra charge).

If you're looking for a gaming keyboard as well, I would look into the Razer BlackWidow. It's a mechanical keyboard allowing for much quicker response, and the keys press easily, making it easier to control your keystrokes, for a nice $80. Note, the keyboard is very loud.

There's a nice shiny version of this as well, that lights every key up blue. It also has options for changing the pulse speed/brightness of the lights (Off, dim, medium, full, slow pulsate). About twice the price of the standard one, but definitely worth it considering all of the features.
