Easy solution, purchase a Vantage system. I install them. Go to vantagecontrols.com for more info. For a mere $6000 to 10,000 more for a home, you can have the maximum utmost in home lighting. It can run the HVAC, audio/video, alarm, lawn sprinklers, all dimmable loads including dimmable flourescent, relay loads, works with any DIN rack systems and the dimmable SCR's go all the way down to 1%. It's a slick system and the up/down of alternate 3 way/4 way switches is eliminated. Each single gang box can be up to 8 switches. The programming is virtually unlimited. Plus, anytime you decide you want a switch to do something different or add/delete a switch, its a simple modification in the program called QLink. End that 3way 4way frustration now, check out Vantage. /forums/images/graemlins/grin.gif
