I use the Turtle Beach Z11 and really can't fault it. The audio quality is great and you really feel the bass with it. The mic quality isn't as good as you'd get from a condenser microphone, but for gaming you don't really want to be using a condenser anyway. If you've seen the L4D2 videos that's the one I'm using in those. The price of that also comes nowhere near hitting your budget.You can always change the microphone sensitivity.
