Movies like this?

I was never a big fan of gore films until a friend of mine showed me "Terror Firmer," the Troma film. I've seen a few other Troma titles, and now this.

So basically, I'm looking for the other good ones in this sort of genre. I'm not looking for serious films with this level of gore, I like the ones where the director has a sense of humor, and the over-the-top gore is funny instead of nauseating.

I'm certainly going to watch "Bad Taste" ASAP, but who are some other good filmmakers who have made this kind of film?
