I was just curious how much they wanted.  I never doubted you were making
something safe.  If I were planning to use X10 in my projects, the first thing
I'd order is your XTB-II/R.  As it happens, I'm pretty well set on going the
ZWave route.  The next decision is how much I want to do with the lighting.
There are nearly 100 circuits I might want to control eventually but only
about 40 are critical.  I've sold a fair number of Leviton Vizia RF (Z-Wave)
systems and so far there've been no problems.

I realize you do a lot with X10 but have you played with Z-Wave at all yet?
