Yes materials can be a problem I imagine...that's a problem with many non HK films as well.
DDDhouse is good and cheap so maybe take a look there?
They've got a Shaw dvd sale (many good titles in there) on now and the Legendary Collection dvd's (look under Fortune Star series) are only $5,many good titles in there but pic quality varies.
They're also customs friendly (think they mark $US 3 per dvd/bd?)
They ship registered and accept paypal.
I'd also buy an Ebola bd (with the censored footage inserted back in please) if it were to be released.
