horror/exploitation boutique labels

[Steven11788]

hey of course I am not new to the game, but I am wondering is there a list on this site or can it start here of all the horror boutique companies.
Of course I know scream, arrow and severan. I know a few more but cant rememer them. I am lucky enough to live near Orbit dvd. IMO the best horror cult geek store period and they have tons of horror titles from, it seems 100s of smaller labels. lots have slips with no indication of what the movie is about on back or they covered up so I cant read synopsis of movie or half way remember title. So I am wondering if we can start a list here or someone point me if this has already been done.
thank yo so much
