I went with The Vincent Price Collection. Abominable Dr. Phibes on Blu-ray was more than I expected from Shout in this one and The Masque of Red Death is an absolute favorite of mine. I'm not a huge fan of Witchfinder General but recognize its rather large fan base and I'm glad it's there for them too.
I'll most likely be getting:
Prince of Darkness
Day of the Dead
In the Mouth of Madness
House of Wax 3D
I'll have to watch The Haunting (1963) first but I'm sure I would pick that up as well.
The combined weight of the horrors I have authored wrought would crush your carbon hearts into perfect diamonds of terror!
A Few Ants Short
