... Back when I got the forgotten worlds panels, Some of them had spinners on them. I think I sold them for like $75 a pop and that was like 15 years ago. I think a recently, somone here sold a pair for $300.
I saw some $300+ CAPCOM spinners last year. They were "NOS." Sold on eBay. And looked real nice.

Anyways, I agree: $75 (shipped) for a used working CAPCOM spinner is about right.
And about $65 (shipped) for a bad FW board set is about right. It will cost about that much (on the low end) for a tech to fix it if the custom is bad. And a working FW board may be found for about $125~$150 (shipped).
Seen some people get around the CAPCOM spinners before by using Arkanoid spinners and wiring a cherry switches to auto fire. But, never seen people get around the cab art. Original Cab Art is always the tricky part. Can't have a cab with out it. I have no idea what all that art is worth, especially all together like that.
Anyways, not sure if this is true or not; but, last year, iirc, a buddy told me that Gene was asking around $300 for a working board set and working pair of CAPCOM spinners. I never checked it out. But, I give my buddy the benefit of the doubt. Hope this bit of hear say can help.
And, right now, FW is more popular on the EURO (Fr) and ASIA (Jp) scene (and not so much the US scene).

Best of luck with the sale, R1.
