Downton Abbey is on PBS. All you need is an antenna, and you can have it for FREE!
I have gotten pretty good as reducing monthly expenses. I built a home theater PC with four tuners connected to an antenna. I pay for basic Netflix streaming + 2 DVDs per month. My internet is naked DSL from a company that does not throttle bandwidth (CenturyLink), and I use MagicJack for phone ($30 per year). My total for everything is under $60/month for phone, internet, and TV. Comcast would happily sell me something similar for around $100/month (for the first year, price goes to $500/month after that).
I would like to get some more channels like SciFi (or SyFy, or ScyFye, or whatever), and Discovery, but it is not worth $50/month for a bundle that includes those.
