I am keeping ALL of my X10 running. Works great. I have plenty installed. But I live in the middle of nowhere so I don't worry about many of the things that affect others.
Not buying new X10, but buying new Insteon. I find it just better than ZWave, and more reliable.
Even with a couple of loads causing some problems with the X10 (imported, inexpensive LED bulbs) I dealt with that with some very inexpensive components, and it all works like a champ. Got it all very, very cheap.
Vera works very well with the Insteon USB module; I had to do next to nothing to get it to work, which was nice.
I just wish there was just a bit more Vera support for Insteon. All the work appears to be going to ZWave devices.
I am buying a different brand controller to see how it goes with the Insteon and X10.
I want to bridge my ancient HAI panel somehow, at least for the ZWave Fire (CO/smoke Combo) detectors. And I have a lot of I/O going through the HAI for sprinkler/pond control.
