Holy CRAP, the Q80 is downright reasonable compared to some of the other stuff. The Dano Coral is a parts bass, the "Tony Hunt Custom" came from old Mosrite parts, and IMHO Mosrites weren't very good to begin with.
But the pièce de résistance has got to be the "Hagstrom prototype." $7500 BIN for a bass never made by Hagstrom.
