I've been in an and out of different scales over the last few years. Built an O high-rail layout (tore down), then toyed with both HO and 1:32 One for a while. I don't like the smallness of HO or N and O is too big for inside running. All the scales have gotten crazy expensive. I've always felt like S was the "right" size but I've been concerned about the viability of it - given lack of manufacturers. What's the current take? My interest is ATSF - late 30s steam through F7s. I'm a locomotive guy.
