RE: WANTED! Your Help recovering stolen Engines! REWARD!
If it was just punks doing this for beer money, I would call every pawn shop in town. I doubt a pawn shop would give them more than $20 for the whole lot. A more savvy thief would approach the professional sellers at the internet auction sites. I hope you catch them, you know the cops couldn't care less about your toys.
My suspicious mind thinks this was an inside job by an acquaintance.
