Looking for a decent starting point for an nscale layout. I've got a mckinley explorer tucked away somewhere, but that's not enough rolling stock for anything other than a basic loop of track. Was thinking about getting the empire builder train set, but I have no idea what the quality is like. I've been out of model railroading for years, for lack of space, and might finally have enough to build one of Mike's door size layouts, looking at either the 3 lap pretzel or the folded dogbone immediately underneath. I know that given the set has been around a while and it's a starter set, the quality's probably not high, but it costs about as much as an n-scale steam locomotive by itself. Is it worth the money?
