Did it something like 10 years ago (when they went digital, we had rabbit ears and 3 stations, and when that went away, that's when we got Roku) and never regretted it.
I would add: get Curiosity Stream! Someone here convinced me to try it and I will always be glad. Many of the documentary series we have discovered stand alone as awesome curriculum, except that in order to retain it, DD12 needs some sort of writing prompt for Q&A, which I then have to generate, which takes time.
