I don't know what your budget is, but Vintage Arcade Superstore in Glendale had several of these. I think they have all sold except one which is running Super Don Quioxote. He can convert it to run Daphne if you want. Give him a call, he's not cheap but can deliver the goods. He keeps a database of people looking for rare games, or who have rare games for sale, so even if you don't want this one, he might be able to hook you up with another game.
A client of his has the CPO and marquee for Cliff Hanger, and might be looking to sell the parts.
Every once in a while I will get a part of two from him and he's always been pretty reasonable. I only live 20 minutes from the store, so it's incredibly convenient when I need a part for a few bucks and don't want to wait for Bob Roberts or an Ebay auction.
His full games are not in my price range....but people do buy them, many from out of state.
