I found my copy of both Fear and Faith and Ghost Hunters. If you're looking to recreate scenes from the GB movies or cartoons, it's worth checking out. As PDFs, they'll cost you almost nothing.
I quite like the earlier Song of Blades- based rules for their simplicity. They work great for new players to learn, and there's enough there for your average tabletop gamer. The more recent incarnations add more complexity without adding much fun (I'm looking at you Fistful of Kung Fu).
