Oddly enough, it looks like one of the Lord of the Rings sets has some great parts for MFZ. Shelob Attacks has lots of clips, hinges, click hinges, and a 2x4 Triple Wedge w/Spider Eyes pattern that I think will see a lot of use. Its also $19.99 USD for 200+ parts, so its in the sweet spot for Price/Piece.
Another Creator set that has good parts is 5763 Dune Hopper.
A super-hero set thats an affordable Price per Piece and has good pieces? Whoda thunk it? 6862 Superman vs. Power Armor Lex is that set.
