I was lookin at a Shark RSF2i on ebay. Never heard of Shark Helmets but it looks kinda nice. Its either that or an ARAI, or maybe a SHOEI, I wanna spend under 400.

 

The Shark RSR2 is used by a lot MotoGP riders now and is Shark's top of the line helmet. Next in line is the RSX and it isn't bad either. In fact, that's what I use and am very happy with it! These helmets never fog up!
