I assume when you say "cable bill" you mean cable and internet combined? My internet with mediacom is around $100 and was around $160 when I had both cable and internet.
I had ImOn for cable only in CR until I dumped them (and CenturyLink Internet, whew, what a mess that was) in December.
Our cable bill alone was over $150. We had a couple of expansion packs (although no premium channels like HBO), an HDTV charge, a DVR charge, and charges for 2 cable boxes. Our CenturyLink Internet/phone bill was about $120 (yes, we were getting robbed, thank you).
We went with Mediacom for internet ($50 a month for the first year, anyway) and YouTubeTV (with HBO Max added that’s $80). So $130/month for TV and internet, compared to $270/month for cable and internet. (That math will change when Mediacom’s introductory rate goes away, but I’ll call and threaten to cancel and see what happens.)
