Do some more looking at arcadeshop and you will find that just about every part of a Pac Man and Galaga can be bought new except the original PCB. They just make new cabinets (for sale empty also) and put in new monitors, coin doors, switching power supply, wiring etc.. and then add an original PCB.
True it's not original, but with the exception of the PCB everything is new - not 20+ years old. So if you just want to play the game in a sparkling new cabinet that's not likely to break down anytime soon and you have the money to spare it's not a bad idea.
I haven't checked the prices, but I bet if you make your own cabinet, buy a PCB off ebay and buy all the rest of the parts from arcadeshop it will end up cheaper than 1,695.
