Yes cost is definitely and issue. What I'm trying to do is that I build an Arcade Game Cabinet, which is in my basement. I wanted to be able to power up the cabinet and have a lighted sign in the opposite corner of the basement light up with it. Don't really need to do it, just wanted to see if I could. I am using a smart power strip in the arcade cabinet, so that when the computer power button is pressed, power then gets sent to the arcade monitor, marquee lighting and speakers. Do they make something that plugs into a standard 110 outlet and will sent an X-10 signal when given power and take it away when the power is cut? Thanks for the help
