Yamaha CS80

OK, let's say up front the guy isn't going to get his Buy It Now.  But 
even the comments from people ridiculing that number suggest it's worth 
$8,000.  

Is that true?  I don't watch them super closely and haven't seen one 
sell for a couple years.  But I've never seen one go for more than 
$3,500.  Twice that?  Yikes, they're not worth that much to me.

I love the CS-80, but other than the glamor pretty much defined by it's 
reputation, rarity, and market value... I don't consider it any more 
desirable of a keyboard than several others that sell in the $3,500 
price range (Memorymoog, Prophet10, etc.).
