Passion Music (whose link you just gave) are a web-based Hungarian music distributor in then UK. I think. They go to extreme lengths to be physically untraceable, and don't respond to email (and you need to do a whois query even to find an email address).

They may well be on the up and up, but I would never buy from anybody who operated that way. It's only a bit more expensive to pay postage from Hungary and buy from Etnofon (Sandor Balogh's outfit) in Budapest.
