The Sine one has the advantage of having a very complete look.
My preference is to use the aluminum face plate sold by some hifi shops or Koba in Chinatown, and just use your own outlets of your choice.
Some tips for those thinking of doing this. There are two sizes, the faceplate for the single UK outlet, and the double UK outlet (same as the Sine one in JB's post). I strongly recommend the double faceplate over the single one. Both only accommodate a single US duplex outlet. The single UK faceplate has a lot of difficulties fitting the US outlet, unless you are willing to cut aggressively into the outlet. You will probably end up breaking off not just the ears, but any part of the mounting tabs projecting from the outlet body.
