Cutting the cable, lets talk options and media setups

I have been reading this thread and I have a few questions. But first a little background. I have CABLEONE and pay approx. $266/month for 150 channels, phone and Internet (150Mbps). WAY TOO MUCH. I know I can reduce that bill by a great deal by subscribing to PlayStation Vue . My questions are:
  • We have the PS4 in the den connected to the Television via HDMI cable how do I connect the other 3 sets in various rooms to get PlayStation vue channels? Do I need to purchase ROKU or similar and install the box on each additional set?
  • If I need to purchase what route is suggested?

From what I know, you can basically purchase any streaming device, as long as it supports PS Vue, that you want for the other TV's and add the PS Vue app onto each one and log in with your account. If it was me, I would get a few Roku or Amazon sticks for the other TV's. That would be the most economical. Just my opinion.
