There's lots of free to air tv on c-band too, but to get both polarities you need a way to change it on your big dish lnb, unless it already has a c/ku lnbf. On the older boxes, changing from an odd to even numbered channel was what changed the polarity, as long as that little motor on the top of your feedhorn worked, you didn't notice it. Best to take a picture of your lnb on your dish and post it for us to see. It may be under a big plastic cover though but that's easy to remove if you aren't scared of a ladder. Analog receivers can still be found, on ebay and places like craigslist, usually for little money.
