WOW! I can't believe it took me 10 months to pull the trigger.
I consulted with a friend who is a techie expert. His input finally got me to do it.
I ordered a Netgear modem/router and three Roku+ streaming sticks. Yesterday I did the switchover. Swapped out my modem/router for the Comcast one and added the Rokus to three TVs. Had to call Comcast to activate the new router/modem and downgrade the service. Had a few false starts doing the software setup but it was all done and I watched the 6 o'clock news and the Red Sox-Yankees game on my new setup last night.
I downgraded Comcast from the old Triple Play bundle to internet only, Added YoutubeTV and I'm done. According to my calculations, I'm saving about $125-$130 per month! I get ALL the channels I ever watched live with Youtube TV and a library of reruns if I'm interested. Also a handful of 30 day free trials for different streaming services such as Netflix, Disney+ etc.
Gonna use the Disney+ to watch Hamilton then probably cancel it before the end of the trial period.
Two points worth mentioning: Comcast was excellent in the transition and very helpful. Other than trying to upset me a couple of times, which I expected. Also, the hardest part of the transition was getting at all the wire connections behind the 52" TV on the heavy oak credenza to unplug the old and plug in the new.
