Regarding ads on eBay for $15000 KISS machines: Even though a seller has the right to set the price as high as they want, I can't help but make a mental list of sellers that I would never purchase from based on these ads. Even if they were selling something I wanted for a reasonable price I'd feel like I'd rather give my money to someone else who isn't gouging the market.
I hear this ALL the time. Machines that sit on eBay as free advertising AND machines that are blatantly over priced AND their condition is overstated are always a cause for concern. Five years ago, people fell for it, but far less these days. People expect quality for inflated prices.
I know people that will pay $8K for a restored TZ, but won't pay $7K for a dealer "reconditioned" game.
