Insteon RF phase bridges ("SignaLincs") have that capability - you plug one
in, press a setup button, then plug the second one into outlets until its
LED blinks the right way (a fast blink, IIRC).  You get a pair of them in
each of the various Insteon starter kits, and they sell individually for
$40.
