To the right people, Beatmania 5-keys are still worth a lot. It depends totally on the location. You can't just say they're worth $100 because one sold for $100 (and that's coming from the guy who won the one for $60 on eBay!). I can name a few that have sold within the Bemani community for over $1k. I'm guessing the reason they occasionally go cheap on eBay is because either they're selling in a super saturated market (California/Texas) or they're not being advertised in the right places (e.g. Bemanistyle.com), so the bidders are just random people picking them up for the hell of it without any hardcore interest in the series.
Incidentally, I'd pay $100 for a nice set of control panels/turntables alone. Or for most of the boardsets/hard drives alone. The PCBs routinely sell in the hundreds apiece on Yahoo Japan, often to people like me bidding from overseas. The Dreams Come True PCB would probably fetch $300+ alone. This guy's prices are not even remotely out of hand.
I agree with a lot of what you're saying bobby. Bottom line is timing and 'where' you put it up for sale. I think I can safely say klov is not where you'll get your asking for this specific game. Still, there are exceptions. As its been hammered out before, many higher priced listings on the bay are retail, and many don't sell. Good thing for you is you have the luxury of holding onto the stuff until an acceptable offer comes around.
Good luck with your game sales.
