These guys make top-notch, super-low-budget spoof horror short films and trailers, which you can download and watch for free.
Check out the excellent Cool Guys, for example. The trailer is arguably better than the movie, but they're both pretty good.

What happens when two lonely losers and one wild party animal hit the beach for some hot fun in the summer sun? Can they learn to be cool or is cool something you're born with? You'll find out in this hilarious summer beach comedy from Astron-6 that holds its own against the other great beach comedies of years gone by (Weekend at Bernie's, Jacob's Ladder, Hardbodies.)
If zombies are more your thing, watch Inferno Of The Dead, which is about a hundred and four times funnier than Sean of the Dead.

Or H.I.Z (Erection Der Zombi), a note-perfect homage to 1970s Italian exploitation flicks.
