The PCS are the best X10 dimmers followed by the Switchlinc's. Just make sure you take care of the basics and buy a good coupler repeater and filter for noise before expecting reliable service out of either. Ocelot's are had to beat for control, but are too slow for doing direct IR control of a TV for things like volume, mute and channel change. They are great otherwise,
