Aussie BluRay $15.98 at the moment. Fantastic movie. If you've never seen it then you must see it just for the fact that Donald Pleasance drinks beer while standing on his head.
Oh, and those who are easily offended by real life animal death might want to skip the roo hunting scene, although there is a disclaimer at the end of the film about that particular scene.
