The Edge 6 tuner cable only is about twice the price of a Refurb Roamio Pro (Weaknees)_with all in service. I have a Premiere XL4 and wonder if I just want the Roamio set to TE4 and the Premiere on TE3, of course, Just what, if anything am I giving up and what happened to the discussions regarding ads showing up when you stream or watch shows. It is so hard to decide! Or TV's can do 4k but I would have nothing to record at 4K. I also use wired Ethernet.
