cant find it anywhere on blu ray

SCORED!!!! just ordered 5 copies in blu-ray for only $17 each

I wouldn't even want one if it was free.

There is a blu ray release, in Germany, the only one available.
The blu ray is region locked B but at least contains a "DTS HD Master Audio" English track.
It's the only edition available, I've also purchased it for a cheap price over Amazon Germany, but trust me it's well worth this cheap price! The sound is so loud unclear, simply awful. And the picture quality is a joke!
Sad since Platinum Collection (the distributor) usually done correct job on their release.
If you are a HUGE fan of the film, or take a copy of it, it's still better than the horrible DVD transfer, but if you aren't a die hard fan of the film pass on this.
