Yep, that's insane. I just re-upped a Comcast 2 year double play (Blast HSI + all channels + HBO) for $110 a month, about $120 with all taxes and fees included. I was on a $100/mo. new customer promo before so $10/mo. increase after 2 years which is not that bad, except they have added another $8/mo. in broadcast and regional sports fees over time.
That's using a single Cablecard in a Tivo + 3 Minis, which means I don't pay their ripoff equipment and outlet fees. The Tivo whole-house setup paid for itself a year ago vs. renting boxes. Plus I get a $2.50/mo. credit for using my own equipment.
I get that same new customer promo every 2 years when my current one expires. It wouldn't be much cheaper to only go with HSI + streaming services (something like $100 a month I think) and I wouldn't be able to auto-skip all those commercials without a DVR. Plus my son uses a ton of data today, we'd probably exceed the new 1TB data cap if we went all streaming.
Streaming is a very poor substitute to a good DVR setup IMO, but I can see why folks like it if they don't watch much TV.
