I've bought stuff from Hong Kong via EBay a few times now without problems. A package was once intercepted by the Revenue, (due to it being sent to my work address I believe), but once I forwarded on the documentation and explained it was a private purchase and not for the company, they just sent it on without charge.
One thing I'd say though, as with other topics on this site, heed the advice that if the offer sounds too good to be true, it probably is. There's a lot of people on EBay making a lot of money out of selling junk!
