don't forget WMQF - a fox affiliate... Also, Al Jazerra, Russia Today, and ABC News Now are nice news channels to have... also GNF Movie channel, JSTV, and lots of others are neat to have... and if you speak spanish, there's TONS of stuff to see (especially if you can get Hispasat, that has at least two movie channels that normally do US released movies either in Spanish dubs or in English with Spanish Subtitles (more of the former than the latter though, unfortunately))...
feeds are nice too...
and yes, not having the cable bill helps out... although, initial investment may cost a few bucks if you go with high end equipment...
It's worth it. We used to pay 110.00 a month for digital cable w/high speed internet... now we pay 30.00 a month for dsl and nothing for fta.. original cost was somewhere around 300-500, counting cost of dish, reciever, motor, lnb, and shipping... we've had the equipment over a year as of about a month ago, and it's more than paid for itself when compared to how much cable or dish network would have cost.
