Do you desperately want wireless? I'm really not a fan of wireless mice or keyboards. All the Microsoft wireless kit I've tried ( two keyboards and three mice ) are universally rubbish. I'm told that Logitech are better, but I'm still dubious, particularly for gaming.
About six months ago, I bought a wired Razer DeathAdder mouse and it's by far the best mouse I've ever had. I think it was about £35 but it's silky smooth, very comfortable, has big buttons in the right place ( why do Microsoft, Logitech, etc all make their #!(*|£& shoulder buttons too small and put them in the wrong place!? ) and glows on and off with a blue neon light which is utterly pointless but cool.
