Phantasm. Tourist Trap. Mondo Africa. Ilsa, She-Devil of the SS. The Devil's Rain.
I think all of these are great, Dave. You're hitting them out of the park (unless you think these are crummy).
By rights,
Tourist Trap shouldn't be as creepy as it is. It sounds stupid on paper but has atmosphere to spare.
I saw the
The Devil's Rain as a "creature feature" on late-night UHF TV as a kid. It definitely stuck with me as well. It's ridiculous, but something about the tone of the thing is intriguing. And the ending is very funny.

Incredible movie. I like Morricone's score a lot.
Fulci's Zombie Flesh Eaters
I'm relucatant to admit that I love this movie, given how inescapable zombie-related business is nowadays.
The Beyond and
The New York Ripper are probably better movies, but I like that most of
Zombi 2 takes place during the day and in the tropics. And Fabio Frizzi's music is something else!
