The AMC website has full-length classic B movies (I'm told there is a way to download them, as well as streaming). There are some goodies here, including a personal favorite called The Horror of Party Beach. No sign of Attack of the Giant Gila Monster, but evidently they add flicks periodically so I still have hope!

Probably not a kilt in sight but wanted to share this treasure trove with others who spent parts of their misguiding youth enjoying fare such as Fiend Without a Face ("It's brawn vs. brains as a chain-smoking, coffee-swilling military investigator fights disembodied, bloodthirsty, atomic-powered brains").
