I happened to have stumbled onto your article via google and saw the powerbridge device. I have been looking for something like that for my new flat screen that doesn't break the bank and it fits the bill perfectly. I went to their website and saw that cables for less is an authorized dealer and they are selling the plain one with the cable passthrough for $55 so bought two. Thanks for this great find.
I can't post links but if you go to the cables for less website you can find it.
