Reccomendations of Headset?

If you can afford to get one shipped from England i'd suggest the Creative HS-600, its around £30(pounds not dollars), and has very good sound quality, nice padding to keep your ears comfortable and a fully moving mic which you can bend into the shape you want. I'm aware in dollars this would be a little pricey, around $60 plus P&P but its a nice investment and it fully works on american PCs, my older PC is an american Dell.
