Jose - If you can get more Casino's to put there machines back in play and get regular new designs you will be the most liked person around. Think back a few years when casino's were saying the strike machines weren't a profit maker for them and then remeber what some people told the casino's, if they had new designs a little more often they would see more play, the casino's that came out with new designs a bit more often had good support from the collectors those that didn't got rid of their machines.
So once again I would say go make a good pitch to the casino's and hope.
