Here's some I enjoyed:
Top Fighter 2: Deadly China Dolls (1996)
Fanex Files: Samuel Z. Arkoff (2008)
Herschell Gordon Lewis: The Godfather of Gore (2010)
Not Quite Hollywood: The Wild, Untold Story of Ozploitation! (2008)
Machete Maidens Unleashed! (2010)
Btw the last 3 all have outtakes included on the disc I think,they're certainly worth a watch as well.
