You need to spend some money or you'll end up with crappy quality. Buy a Plantronics one or something else that's been well recieved by gamers.
It really depends on how much your willing to pay also. I'm not sure but this one looks okay for the price: http://www.tigerdirect.ca/appl ... pNo=4185325&CatId=390
For the price the creative fatality headset is good! As siad above Plantronices make some good headsets too or the Steelseries 4H is a good mid range headset!
