I paid in the 300 range for my shoei X-11. No way in hell I would pay $800 for a helmet.
I have a KBC VR2 and the X11 is much better as far as comfort, fit, and how it feels at speed. Its as close as you can get to not wearing a helmet to me, plus it cuts through the air perfect and you can turn to the side and not feel like your head is blown off.
