Arai Helmets

Hi,

I've been looking at various places to buy a new Arai GP6 helmet and have found the least expensive are on ebay from Japanese sellers.



Is there any reason not to buy from these sellers, the price difference is not trivial? Could these helmets not be marked correctly for use in the US?



Has anyone else had any experience with buying from these sellers - that they'd admit too?!



Thanks,



Ian
