"A lower-cost system aimed at the mass market, this guy features a ZigBee-compatible controller with remote, a SideShow-combatible in-wall touch panel for all of your fave widgets, and the usual control switches, dimmers, and thermostats. The system starts at around $825 for the PMC2 controller (up to 100 wireless devices), PLX2 remote, and P-MNETGW wireless gateway." - Alan Cheslow from Bookmarklet
