For alot of years I simply cut off the mounting tabs off a 3-way x-10 switch and placed it in the back of the switch box, and put one of these modified decora swithes up front. It was a good looking, great feeling pushbutton decora switch that did the trick. Don't load it up too much as the mounting tab acts as part of the heat sink. Mine were usually controlling a 60 watt bulb, so this was not an issue. I was lucky enough to have deep switch boxes, but if you don't, the unit fits well under a light fixture. Very similar to the x-10 inline module, only with a third wire for remote 3-way control.

The switches I modified were leviton. I don't have a model number, but they were spec grade, and usually under a couple of dollars.
