Hi: Ebay, and other Internet sites, are really useful for "S". There's usually 20-25 pages of American flyer on ebay. My local hobby shop doesn't have 25 individual items. The prices I pay are mostly above the “Greenberg” price, but then, the prices I see at the GATS shows I attend are too. Sure would like to know where Greenberg buys HIS stuff. But, I’ve never paid more for an item than it was worth to me. Regards, Ted .
