Personally I'd recommend the Death Adder V2. I'd still be using mine if I didn't own my L-trac. The L-trac is simply the best pointing device I've ever used and haven't gone back to surface tracking mice since, it's like comparing a kids toy with an oscilloscope. Regardless, just buy a mouse with the feature set you need. Logitech makes good scroll wheels, and steelseries is highly recommended as well.
