I have used mine for only one project, a 1/8 scale pre-WW1 race car. It turned out very nice, and the PE set was the only decent way to make some of the parts. But that was a major, major project, and I seek a way to get scratch PE parts for projects that are not that much of a project. And, it would be nice to get some bigger pe pieces. I am working on a diorama that has a steel girdered bridge about seven inches long, where PE is the obvious technique, but I just don't get around to it because of all the work, and the fact that the MM set will not make parts that big.
