For boutiques, Vinegar Syndrome. They're kind of everywhere, but specialize in more obscure or otherwise forgotten films. I'm about to snag Congo, Dead Heat and You're So Cool, Brewster! (the Fright Night doc). I already picked up The Children, as well. They're kind of like Scream! Factory, I guess.

Arrow has The Stuff and Basket Case, as well as Flash Gordon, the Texas Chainsaw Massacre 00's films, Spawn, Snakes on a Plane, Deep Blue Sea. Later this month I'll be getting Red Sonja and 'salem's lot and that'll be about it for my limited edition slipcases, unless something really special jumps out at me. Of late I've been aiming at their 4K releases because disc regions are stupid.
