The question that seems to remain unanswered is whether or not X-10 = Plug N Power. I didn't see the letters X-10 mentioned on any of the documentation that came with my Plug N Power stuff. I also noticed that there seem to be seperate X-10 and Plug N Power modules, receivers, etc. on the radio shack site which confuses me more. Anyone know for certain? The price difference is small if anything, so I would be glad to return all of my Plug N Power stuff to get X10 equipment.
