This quoka.de site often has very attractive offers and you know what they say when something is too good to be true..... I've been burnt there once, so buyer beware.
I agree $14.0000 is a ridiculous price, but at the other extreme so is €2300, unless it has serious 'issues'. The market value of the PS-X9 should probably be somewhere between $5000-8000, depending on condition. This puts it in the same bracket as Technics SL-1000 mk3 and Pioneer Exclusive P3, the major competing statement DD turntables in those days.
There's one other Japanese tour de force DD table that would probably exceed this price level: the much rarer Denon DP-100M. Incidentally, there is one up for auction on Yahoo Japan. Current highest bid is only $3460 with 2 days left. I'm tempted, so very tempted......
