Mondo Bungle

Well assuming Braindead doesn't count since it's pretty much the be all end all of that, I'd say:

Dawn/Day of the Dead
Versus
The Evil Dead
Burial Ground: The Nights of Terror
Bad Taste maybe (It's Zombie-ish but they're actually aliens)
Dead Snow
City of the Living Dead (many many Fulci movies qualify though)

also Blood Feast ought to be a priority based on historical value but I prefer the Gore Gore Girls which he did like ten years after so you should watch that too. And I guess the Wizard of Gore. That's the trifecta.
