Assembling my own Vincent Price Collection Vol.1(OOP)

[Bladerunner5375]

Hello, Gang! Since the Vincent Price Collection Vol.1 by Shout Factory is OOP, I've been thinking about assembling my own version of the box by buying individual releases(all of which would have to be imported). This being the case, can any of you who own the following movies in their individual releases tell me which company has the best version of each(PQ most important). I am region-free, but I'm looking to buy the best version of these:

THE PIT & THE PENDULUM

THE MASQUE OF THE RED DEATH

THE HAUNTED PALACE

THE FALL OF THE HOUSE OF USHER

THE ABOMINABLE DR. PHIBES

WITCHFINDER GENERAL

If anyone has the Australian version of the Vincent Price collection, is it worth buying? Is it region free? Thanks in advance, my friends!!
