Edit: Also, I disagree with the people saying that wireless is a bad idea. Sure, you may have to recharge them (some more often than others), and they are probably pretty heavy because of the batteries, but if you need a wireless mouse, I think it's worth the "trouble". In terms of responsiveness, I don't think you will feel any difference between a good wireless and a good wired mouse.

wireless mouse will be always worse than a wired one (someone said twice)

FPS and wireless do not really match. My two cents on the matter is stick to wired and get any of the Zowie mice. Awesome quality, best optical sensor. Mouse developed with the help of pro players :)

Buy a good mouse mat and most of your problems will go away. I use 6-8-dollar mice for over a decade and I never felt them to be slow or imprecise, mostly because I use a cheap textile mouse pad.

Im happy with steelseries rival 200. Mouse has issues with rubber on sides, but overall its must have)
Rival series has 100, 200 and 300 models. It depends where do you live, but 75$ is more than enough anyway
