Thanks because you don't know the cost of doing business. You would save almost no money if you went above 9 channels or so and if you figure ABC, NBC, CBS, FOX, WB, UPN, PBS (just looking at locals here that MOST people want) that's 6 channels right there. Now, start factoring in that you may watch SPIKE, History, Comedy Central, ESPN, ESPN2, ESPN News, FSN (local sports), NickToons, Noggin (my daughter), Discovery, TNT, TBS, A&E, FX, SciFi, FOX News.
Some cable channels will probably be about a $1-2, while the more popular ones and sports channels would be around $2.50 to 3. So with just the channels I listed above I would be paying $22 - $45ish for just those channels and I it will probably be closer to the $45 as ESPN already charges around $2 a sub to cable companies just for ESPN and not including ESPN2 or ESPN News. And that is just for around 22 channels that I came up with off the top of my head randomly.
So if you only watch 7 channels then you are good.
