Quote from Sinbad sale description on eBay pretty much sums it up.
"I've looked around on eBay and found one for $4,250
After talking to some people who know about this stuff, they said to put the $2,995".
People see an asking price and think that's what their machine is worth. Sinbad is a cracker of a game, one of my favourites but in average condition like this one it's not worth anything close to this asking price and its the same machine that was listed for almost 3 times this price only a week ago. They do have a "make an offer option" so I guess at least they're willing to negotiate.
