Ebay has seen a flooding of the ROS foils for the last several months from the seller weshipfreely (second account of wildthingsgames who sells complete sets). This flooding has driven ebay prices way down (around $80 for the first wave to around $15-20 now). Although they are selling cheaply now, there value to most players/collectors is higher than the ebay prices. Unfortunately, you'd be lucky to get more than the current ebay prices.
