Gilly@N&W,
Boy, do you have a point about public displays. It really doesn't matter what you run, because a lot of folks can't tell the difference. So you might as well run something that is sturdy, conventional and hard to break.
The only exception for me at two recent displays has been the LionChief sets and the Lionchief steamers.
They are easy to run and the public really likes what they see.
