A friend and I actually each bought one from him. I have his contact info if anyone wants it. He had two left last time I spoke to him. They were in pretty good condition, I'll post some pics of the one I bought once I clean it up a bit. The entire top of the control panels are not original, they all have Happ knockoff parts and plexi and laminated paper CP's. They look like they're from a closed down Nickel! Nickel! arcade. They had a bunch of these machines set on free play in the back, last time I was at one.
The machines are on metal stands to raise them to standing height, but are easily removed from the stands. They also have metal covers covering the front of the bottom of the machine. (where the access doors are). There is a hole (about 1/4 inch) drilled through the large access door to secure the large metal panel that has a sticker that says "free play". The two we bought work and play fine, nice monitors, very little burn in. If anyone knows were I could get an entire top control panel for an Aero City, It'd be much appreciated.
Oh as a bonus, the one I bought had a Ghostbusters board. Don't really care for it too much, but something different I suppose.
