I 100% agree with Marty. I am fortunate to have a cab-2 that works. I sold my cab1s as I no longer needed them. I also sold my DCS remotes too in favor of the MTH DCS app. I had a brief setback when one of my WIUs was not working but that is resolved.
Let's see how the base 3 evolves. I will buy one at some point I am sure but right now, even if available, I don't see any must haves.
