Do you want the actual Inlet and Outlet used in the PowerBridge (PB)? Your DIY project could be cheaper 
Some sources (links) for purchasing are listed in POST #6
Forum Member ToxinLab was able to find the Inlet for $11 at his local electrical supply house. You should be able to build a DIY PowerBridge for under $20.
Part #5278-SS
Available in Gray or Black (PowerBridge's White Kit option is also Gray inside the hole if you look).

Gray Inlet: Part #5278-SS, Black Inlet: Part #5278-SSBK
Though they are using a 'rubber washer' with adhesive on both sides to mount the inlet to a wall/face plate with a round hole, you should be able to figure how to glue it on.
Add remodel boxes, standard power outlet (or use the actual one the PB has: Part #5251-W - see below), a 2nd wall/face plate with a round hole and some Romex wire and you have your own PB DIY project while saving some $.
If you would rather have the convenience of purchasing a complete kit and $ is no problem, just buy the PowerBridge Kit. I did and recommend it. The extra $25 is not a big deal IMO...

Other colors available!
You need a recessed box adapter if you want the plug recessed like the PB. If you do use the recessed adapter, the metal is cut off just above the first screw holes from the outlet (1 on each side). Those two screw holes are used to attach the outlet to the recessed adapter.
Here are some pics showing the PowerBridge up close (you can see how the Inlet is mounted to the wall/face plate).
