I don't know how active this site is. I found it many years ago went MX-500 ->700->850. Wow the 850 lasted for me for a long while. The 850 is worn, and I have bought spares to keep it going. But I wonder what I should do now. Questions-

What model? I am a diy'er

Can I copy the remote profile to migrate to a new remote? Even if I move to a complete control remote.

or should I give up on URC and move to Harmony or get a global control and build the remote from scratch using an iPhone for the remote.
Many thanks.
