Once again... if money is tight, no need to turn to cable even for internet service. We get DSL service for $19/month, without adding home phone service. It isn't as fast as cable, but then again it does what we need fast enough and our house includes 2 network laptops and an Xbox live bandwidth eater.
For DVDs, there's Redbox. Get a couple of free rentals a month and the rest of the time it costs $1.20. If we can't watch a DVD on the night of the free rental, we have a solution for that too which costs us an additional 40 cents.

For those weeks when the Flyers are in the playoffs, usually can catch the games on NBC or we call up some PA friends and go out for a few beers. Still alot less than PPV and a monthly cable bill.
Same thing for our alma mater football/basketball games. When the game is big, we meet up with our local alumni assoc to watch it somewhere else.
Not having cable has actually contributed to our being more outgoing social people in our old age.

All Texans games are broadcast on local HDTV, by NFL mandate, even if their game is showing nationally on the NFL network or ESPN. And local HDTV shows way more Astros and Rockets games than I care to watch each year.
Finally, with 2 kids in high school, a lot of our time is spent at their games and competitions instead of sitting in front of our HDTVs. We much prefer the
Real Friday Night Lights to the one on TV(when it was on TV).
All in all, NOT having cable TV has probably enriched our lives.....
