I'm not sure I understand the lack of interest in the current $40 strikes. Linked below is a $40 Mirage and there is a second listed with no bids.
Many people complain of the extreme cost of winning them yet this does not seem to be reflected in the auction selling prices. The $40 LVC from the tournament seems be languishing as well. There was much excitement when Caesars and later the Mirage put the $40 strike back in play.
