I always bought my X10 stuff from local (Baltimore) dealers until X10USA decided not to sell the CM15A/AHP to local X10 dealers. The one I patronized for years was Pigs Electronics in Perry Hall until the guy who owned it decided to get out of the X10 business and sold off his inventory. He did a good business for many years, though. I only bought my CM15A/AHP from X10USA because my local dealer could not sell it.
