Thank you all!
Jim is right, I am just looking for someone to help my wife's friend dispose of the AF trains to someone who can appreciate them, but give her a reasonable amount of cash in return.
Gary and Ray, As for S Gauge, yes it does look appealing when I try to plan for all I want to run in a small amount of space. I am no stranger to changing scales, as I stated. I have had HO, then N, then HO again, and finally O 3-rail, with a dabble into HOn3 and On30 thrown in for fun. However, I have a nice collection of O gauge now, and don't have the space to run S as well. I'm an operator not a collector.
However, one never knows. The first toy trains I saw were my uncle's American Flyer trains as I was a pre-schooler. He moved away when I was 5, and I didn't see them after. I could end up going full circle to what he had. ???????????
