Here is a little tip that may help some of you. I was trying to make my power strip and wall warts as short as possible. I wanted them all to fit under about 2.5" space. That was hard to do. I found some extension cords that had the low profile (go to the side rather than straight out. I cut them to be much shorter (6" or so) and then replaced the outlet end with one from the hardware store. That allowed me to make a little pig tail, so i could place multiple wall warts on the power strip and not have the wall warts sitting ontop of the power strip.
