Insane auction price of SACD?? over 2k

Ahhh the web. Since the Sony Es777 SCAD player can still be found at a few dealers as demo's etc for like $1,700, why are bidders going crazy over this one??? Just LAST NIGHT I put thier demo unit on lay-away at my LOCAL dealer for the amazing price of $1,700 and I get the full 5 year warranty and the selling dealers service. Now I can't believe that the one I bought was the LAST ONE IN ALL AMERICA. If you want one CHECK AROUND at the Sony ES dealers. GEESH.
