I highly suggest the Logitech G9x. It's a gaming mouse that's as simple or as complicated as you want it to be. It will plug and play, or you can customize your own profile if you want to.
It has 4 on the fly sensitivity settings, you can change the shape of the mouse, change the weight, and it has the both clicky mouse wheel or you can set it to smooth.
It's $70 at newegg.com right now, or wherever you want to look.

Edit: I've had mine for over 3 years now and the only thing that's happened is the left button is discoloured from use.
