Being as tech savvy as you are I'm kind of surprised you just now "cut-the-cord."I was on a legacy plan getting 80Mbit/sec for $50. Now I have 200Mbit/sec for $65.99 a month. That's the slowest package they offer and I couldn't keep what I had.
May "triple-play" from Cox was $287/month for cable-TV (2 HD boxes, 1 w/DVR) + Landline phone + 150/10 mb/s internet. Dumped cable and phone, bill now $98/month. I should have dumped cable way earlier. Save about $120/month net, after added cost of Netflix, Hulu (no ads) and YTTV. Actually will be $150 month savings once I drop YTTV and get cheaper replacement.
My internet is nearly 50% pricier than yours and a bit slower. So your $66/month isn't too bad really. My bandwidth cap is 1024 GB/month. $10 for 50 GB overage "fee." Usage 450-900 GB/month with avg around 650 GB/month. One heavy TV user, one very light TV user, one internet user.
What is your bandwidth cap? Overage fees? You should be fine unless you have some ridiculously low 250 GB/month cap.
Streaming services. If you want local channels, ABC/CBS/NBC/local channels, etc you have "Hulu Live-TV" or YouTube TV. Hulu has a crap interface, YTTV has good "live-tv," but crap VOD service. I'm dumping YTTV soon as their VOD is crap. I just don't watch the locals enough to make it worth my $50/month. I looking at Sling (blue) or Philo to replace YTTV, which will save me another $30/month.
