It's not the fact of where its sold, its whom is the manufacturer.
Just, if you have any issues with the purchase, damaged shipping, etc - you can pretty much count on having 0 customer service. Once an eBay transaction is done - that's it.. you're forgotten about.
So - if you want customer service and re-assurance, then purchase from a reputable place. Otherwise, best of luck with eBay.
BTW - I do sell PLENTY of hoods. See www.sc-customs.com
