A friend and I both have a 424 and we both use a hard thrift store suitcase to transport it around. He wrapps his up in a blanket inside. I got a little more nerdy and went to JoAnn's fabrics and bought a few feet of 1" and 2" thick foam, and cut it up for a perfect custom fit. I bet I could drop the thing 20 feet and it would be fine. My total cost was probably about $15.
