I have used...
Razer Carcharis - Was OK
Creative Soundblaster 3D Sigma - Was OK
Steelseries Siberia - Was Nice
Corsair 1500 - Is OK
I recommend the Corsair 1300 though. It's pretty damn cheap ($5 lowest I've seen) and it works pretty well. My personal setup is pretty ingenius though... I bought a cheap headset for $5 wrapped it around my monitor and have the mic facing me and I use high end IEMs.
Brands you want to avoid though are Razer (overpriced) and Tritton (super overpriced). Turtle beach is OK, though I never tried it.
