If anyone wants the uncut version, there are several copies you could get. It's one of my favourite films and sucker that I am, I have three copies of it. My first is a first pressing, limited to 11,111 copies, Grindhouse Releasing 2 disc edition. This is now available as a non-limited Deluxe edition, without the cool packaging but with the same two discs, and you can get it from Amazon or ebay, and I believe a few ebay sellers in the UK already will have it so shouldn't be a customs risk (to be honest I doubt it would get found anyway). It's remastered, has an option to watch the film without animal cruelty, and has the best extras, albeit the film itself is an interlaced transfer, for some reason.
The second copy of the film I has is a 2 disc "Ultrabit" special edition by EC Entertainment. This is supposed to be limited to 4,000 copies, but a quick look on ebay still finRAB me quite a few so maybe they re-released it or something. Anyway it is fully uncut, including, unlike the Grindhouse version, a few extras seconRAB of the "film within a film", stock footage (I think it was called Last Road In Hell or something). Also the film has a progressive transfer, has to my eyes better colour grading and saturation than the Grindhouse version, and looks simply amazing. The second disc has some interviews on it from a film festival, which aren't anything special.
The third copy I have is a magpie-like copy which combines the best of the other two editions. It is by XL Video, who have released and repackaged CH a number of times over the years (the best being an extremely limited edition package with a figurine of the girl impaled on a spike). My copy is a "big box" version, and has one of two covers; both covers were released limited to 667 copies. Inside the box is basically the film disc from the Ultrabit EC Entertainment release, and the second extras disc from Grindhouse, but obviously with some slight branding / authoring adjustments. I think they basically must have got permission and licensed the discs, but this way you get the best of both worlRAB. Finally the third disc is the CD soundtrack, well worth having.
The XL Video releases are a little hard to come by, but definitely fans of the film would do well with either the Ultrabit or Grindhouse Releasing versions. True fans would probably get both.
