Arkay, what is the country of origin of most of the western stuff you come across there? Did/Does HK have its own pressing plant(s), and how good are the HK pressings?
Some of the popular titles were pressed locally; the most common are the EMI titles pressed in Singapore, for distribution in Singapore, Hong Kong and Malaysia. Hong Kong used to have a vinyl pressing plant (or more?) that did Chinese stuff, but it is long gone; I don't think it made it past the sixties. Most locally-sold titles were made in Singapore, as far as I can tell. Not all Western artists were pressed there, though; only the most well-known (=commercially worthwhile in this region) ones were.
However, I try to avoid those, and when I get them in bulk buys, I mostly pass them on, rather than keep them.
They aren't necessarily bad, but they usually just aren't as good as the American, European and Japanese pressings. I have a lot of each of the latter, with the European pressings being mostly from the UK and Germany, with a few from Holland (mostly Phillips) and elsewhere (France, Spain, Italy, Scandinavian countries - the last ones mostly Scandinavian artists). I haven't counted them, but I'd say I have the most US pressings, followed by Japanese and UK, and then the rest. But if I weren't checking and choosing, I would otherwise have ended up with a lot more local (/Singapore) ones, I'm sure. One cool thing about Hiong Kong is the colonial history and all the expats who lived here. Many of them brought their record collections here, then --after CDs became popular-- left them here, so I was lucky enough to pick up things like a half-dozen original UK Parlophone Beatles records, for cheap prices!

Unfortunately, such finds are increasingly/very rare these days, even here.
