Go with altech lansing, they have great products. I've had my headset for 2 years now from them, and for $20 it was a great deal.
If you're into FPS ( I know you are >_> COD4 deagle'd you) then get a nice keyboard as well. I have the original Logitech G15 (Not the new stubby orange one), and if you can find one of those, it's coveted as one of the best gaming keyboard ever made. Might cost a good bit, I dropped $100 on mine when it first came out a long time ago.
