The good thing about W.B. they usually release their films region free.
I really hate all this region locking there is no need for it.
Shout Factory have some great titles but again they have a "lets keep all this in-house" mentality.
As for Deadly Freind, I think it's a good film sadly it never got the same praise as Wes Craven's earlier work being a A Nightmare On Elm Street Collection [DVD]  and your right it has never been availible on DVD/Blu-ray format in the U.K
Also "Eyes of a Stranger" is a good film love the fish tank scene!
I agree with sellers charging huge sums for films it's crinimal.
