I would say they are bendable, lighter and more durable but not collapsible. The main difference is I wouldn't be afraid to throw them in a bag together and worry about breaking or paint issues.
As far as the cost goes, yes they are expensive, but what isn't anymore? I spent the good part of an hour on the phone with Dave a few years back and realized I was supporting a guy with a small shop that has a ton of artistic ability creating custom decoys in America. I'm okay with that. :way:
