What makes you say that ? I'm in West Chester PA and the arcade vendor is very close to where I live . We've worked together at classic game conventions in the past, he's very reliable and professional (as am I)
Shipping costs for boards not in the plastic cases (forgot to mention these are all bare boards) is about $20 per board within the USA. I've seen eBay shipping costs from a dealer in Mexico who ships to the US full CPS2 sets for $40 so I guess "king's ransom" is a relative term based on what you consider to be reasonable
@MarkWolfe, update your profile with your location. Someone might be able to help you pick these up locally. Shipping 4 boards and 1 A board is going to cost a King's ransom.
