Wireless.
Don't get a wireless, they take a stuff ton of batteries, get a laser corded one, i personally have a Logitech 1000 dpi one, and am very happy.
Logitech HyperScroll High Performance mouse.
Mine doesn't. I only have to replace its batteries about once every three to four months or so, and I use it quite a lot.
The logo on it made me get sick. :(
