Ah, good to know about the Mk4 SSFP. That was the crucial thing for me.
My MK4+NTE5C combo, fitted without my agreement, but what can you do, is not in a place where it’s vulnerable to knocks or disturbance. It’s moderately high up on the wall, and a 1m cable goes into a modem on an open rack right next to it.
What’s cheap about it?
