For years I refused to even mention the name Harmony.  I despised them, the way they programmed, the way they worked...

I've run into a few of the newer ones on jobs where I was asked to add stuff and was impressed with how far they have come and how well they worked.  I still have not sold one, but to be honest, they've shown more growth and willingness to change then all of the big players in this industry.  I would not worry whatsoever installing one nowadays if if the job called for a less expensive solution.
