Ok no affiliation here and both Comcast / Xfinity and CenturyLink are monopolies here in Colorado in my opinion but if you’re an Xfinity customer and just need plain old internet / no TV they have a great deal for 2020, a $45pm deal valid for 1 year that goes up to $55pm after that. Speed is 100Mbps up and 5Mbps down, fine for almost everyone (we run 10+ devices on our network and it’s fine) Of course you’ll need to be running your own modem to get most benefit financially (I’ve had the same old Arris modem for the past 5 years+) and at these lower speeds you don’t need a fancy cable modem with tons of DOCSIS channels.
If you need to purchase a modem here is a list of approve modems for Xfinity as of 2020. I’d get the ARRIS SB8200 ($140 on Amazon) if I were in the market to future proof my purchase but we’ll all be waving these monopolies goodbye in 2 years when we get City of Boulder gigabit fiber for $50pm – I hope 🙂
