I don't believe anything the Facebook x10 guy says about the the CM15A or other modules. I've made 4 orders in the last few months and asked questions. They all came right out and said no more CM15A's. One sales guy told me to hurry up and find one on Ebay before they are all gone. So I found one at Automated outlet and now they are sold out. X10 is now selling a new security system and IP camera that is not compatable with X10 modules. I like what HA Dave said about his cable company and security systems. My cable company Xfinity called me this week, bragging that they had the best cheap security system, and it would turn on and flash lights when tripped. I had to laugh to myself. It basically does evert thing that X10 can do. Turn lights on over the internet, monitor cameras, use your iphone. It was $199 + a monthy monitoring fee.
When the X10 facebook person says they are just out of stock, I have to hold my comments. Maybe they are trying to find a few hundred is storage someplace. But after that I think they will be gone fore ever, that's my guess.
Well..... I have lamp modules and timers that are (Radio Shack) 25 years old and still work without a glitch. I purchased a CM15A and some other x10 stuff so I'm set.
Good Luck All
