Wow.....what a DB
I wish I had had the presence of mind to ask your question before I spent the money on a SCUBA travel bag. I have since paid $35 on a large end of line suitcase that hols more AND does not have a bulls eye on it for those looking for things to steal. Jeff's answer here (and others) are good ones. Heed them

Light, durable, inexpensive, exact size for checked baggage and they have wheels. They also have the advantage of NOT looking like scuba gear.
Use plastic zip ties to latch it, and tape a few under the lid for TSA to re-seal it. I usually put duct tape over the latches, as well.
