IIRC there was two runs of the overlays. One was pretty shaudy while the other one was beautifully created by Phoenix Arcade for IPB. It's a rarity to find one though. Mr Pinball is your best bet for the overlay or post on RGP.
IPB did a run of tables for FH awhile back. I believe they still have stock left. Last time I checked I was quoted $650 shipped. I heard at the shows Gene was blowing them out at $500.
