Thanks for the advice, dvdmike, but the UK is region locked and also lacks lossless audio. Also, the Japanese is quite expensive... as seems the case with most JPN imports.
I just can't find info on the releases I mentioned- French, Hong Kong, and Canadian. Those happen to be the most reasonably priced, and, if they're equally good for the main feature (already have the DVD for the spec. features), I'd rather get those.
I happen to be going to France soon, so I also plan on picking other exclusive titles when there such as Army of Darkness, Suspiria, Tenebre, Inferno, Zombie, Terminator 2, the Transporter films, and the Fifth Element...
