Thanks for the information clp. Another question...I'm what I like to call "electronically impaired". I know the very basics about electricity (i.e. don't pee on an electric fence, don't stick your finger in the electrical socket, etc.). I have no clue what this DC8/DC4 stuff is, X10 modules, noise filters, etc. Does the Jr come ready to plug stuff in for the "electronically impaired" people like myself? All I have are 4 light ballasts, some pumps/powerheads, heaters and fans. If I wanted to use up to the 12 maximum outlets do I need to order additional plugin things? Sorry if the questions are a little on the elementary side but, like I mentioned above, I really have no clue when it comes to this stuff. Thanks.
