Pirate board (classic pirate from back in the day... at least not one of these new bad emulation ones) and a converted cabinet with cut artwork from something.
I wouldn't pay more than $100 US for this myself... $30 for the monitor, $60 for the board and $10 for the cab. But thats just me.
Conversely if this was an authentic Bally/Midway board, cabinet, control panel artwork, underlay, etc.. I would pay up to around $300 for it to add it to my collection. (with ebay resale value between $700 and $1000)
