Providing you take note of the FAQ article above and keep your wits about you you should be ok.
The item seems genuine and the seller has a 99.4 rating from 1000+ sales and has been an ebay member since 2001 which is good.
Ask about a returns/refund policy and what the postage would be to the UK.
I also note that there are 28 bids already so don't pay more than you are prepared to if you decide to proceed.
I got my BB from eBay too but from a Uk seller and all went well.
The decision is yours. If you do proceed do not leave feedback until you are sure that all is working as it should be.
