I went with the Logitech G930 which is basically the wireless version of the G35, and I'm pretty happy with it. I paid about $87 for them after rebate. The software was a little buggy at first, but the newest update and interface has helped with that a ton.
The price on these is volatile to say the least. Every week or month one of the online etailers runs a special on them that drops the price down considerably. In December Logitech had them for $89 delivered. The trick is finding out when there's a special going on. If you check out Slickdeals on a daily basis, or google the headset once a day, that should tell you.
