I checked out the Pegasus website. Sadly, no miners set. They do have a few buildings, but they are HO scale.
I did like the prepainted figurines, especially the indians and the fighting gladiators.
I have two round areas in my layout where I can put accessories. I may put an indian camp in one area, and (no kidding), a cowboy scene in the other where cowboys are sitting on the rails of a round horse pen, watching two gladiators fight inside. (I like whimsical stuff!)
