New Craftsman Propane Trimmer

While working in my office today, I heard several commercials for the new Craftsman propane-powered trimmer. I did some research, and it looks like a very interesting tool. It uses the common 16.4 oz cylinders, and I am sure it is easier to use (cleaner, starts easier) than a conventional trimmer. I wonder how it will sell? At a sale price of $239, it seems fairly expensive. I am not sure if you will save $ over the long haul buying propane and not gas. I guess we will see how it sells.
