We are in the position of being primarily involved in the custom home market, and my short experience over here has found that the homeowners tend to prefer the "Stereo Guys" sticking to home audio and theater, and leaving the high voltage side to us.
We mostly use either Litetouch or GE-Smart equipment for lighting control, depending on the situation, and other than some supply problems when Smart was bought out by GE earlier this year, there is not much negative feedback to report.
I was in Minneapolis a couple of months ago for the CEDIA convention, and was actually quite surprised at the number of Electricians taking datacomms and other low voltage courses, and most of the guys I spoke to felt this was an upcoming market with some great potential for our trade.
Only time will tell...
