SteelwireMantis,
I'm assuming you're aware of this, but nearly 300 (possibly more) of the Shaw Brothers titles have already been released in beautiful editions in Hong Kong, fully restored, remastered, english subs, occasional extras, etc. I can't imagine you'll find a better price than you will getting these Region 3 versions. Despite the Region 3 labelling on the packages, I have several that are, in fact, all-region, but the best thing is to buy a region-free DVD player (available online prehacked or in stores, which you then find the hacks online at places like
www.dvdhelp.com) and eliminate the need to restrict yourself to new Great Britain releases (and prices) for titles that have, in some cases, been available for years now, including 36TH CHAMBER OF SHAOLIN, which is already widely available, as are it's sequels.

CD-WOW, which I believe is a British company that ships out of Hong Kong, also offers many of the Shaw titles for a very reasonable price.
