Enjoy your new showcase cabinet.
No doubt! I even did a little surveying before hand and most people seemed to think the price was decent at $500. I thought $400 would be a no-brainer for someone.
The arcade market is kaput.
I disagree with kaput, it seems the market is coming back slowly and prices are on the rise.
Ebay that thing and set your reserve at what you want.
Plenty of people would pay that, those are nice.
Its all about your target market
Price seems fair to me, for someone who does not have the time or skills to do it themselves, instant arcade controls.
Best of luck.
