I would get the Anderson. I would have no plans of actually flying an airplane with it, so the fact that it's a great example of craftsmanship is the determining factor. You can look at this and tell that it was made by the guys making Norden Bombsights and other precision stuff in WW II a few years earlier. It's just beautifully made. The Super Cyke is a good engine, but doesn't have that same look about it.
Some of the very early Post-War McCoy has the same sort of look about it. It's kind of a shame that that was lost and we ended up with crude slag blobs like the Fox, and the McCoy bubble-pack engines. The Fox and McCoy were better performers, in general, for stunt, but they certainly were not works of art.
