Thanks for the offer Luca, unfortunately I'm in the same boat, I used to able to convert NTSC>PAL VHS but no longer have the player.
Doing some looking around, there's a (still sealed!) VHS on an Italian site, but it's 60 euros. There's also a Spanish release and a south American tape (I can't remember from where exactly) - Also, an American release as 'The Possessor' and the old UK release (as Exorcist 3)
The Italian audio track is fine, I think it's just the video side of things that could do with upgrading - Can anyone post some caps of the UK release? This would be ideal because it's a PAL master, and no on-screen subs.
Does anyone really know which one offers up the best print?
