Satellite Programming for Free?

Frank Winstead asks: "I stumbled upon some "Free to air" (FTA) satellite television references on the web, mostly selling equipment. There seems to be a lot of non-English programming available subscription-Free on the Ku band. The English programming seems to be a mix of religious shows, network feeds, and unexplained content from American over-the-air TV stations. Is it worth a one time ~$200 investment for equipment? Is the authoritative info on FTA?"
