I totally agree that the best horror b-movies are from the 80s and early 90s (for a few). I'll definitely check out The Boneyard.

Over the past few weeks a watched a few oldies.

Maniac Cop
April Fool's Day
Sleepaway Camp

One that I need to watch again is Chopping Mall. Last time I've seen that movie was like 20 years ago.
I'll also give you Bone Yard movie
