Simply put, in my experience and knowledge – cable TV is prohibitively expensive. I know someone who has cable TV, and her TV bill costs more than her rent. In my opinion, your rent should be the most expensive bill.
What I Do
I have a 32″ Roku TV. I plug in a flat panel antenna and set that against the Window. I get all of my local channels, and with Internet ($10), I can stream Roku channels. To me, there is no justification to pay more than $200 to watch television. If you do have cable TV, you are crippling yourself.
