Well, with FTA you have a bunch of choices, look at lyngsat.com and look for the sats in yellow I believe (the ones that have no encryption) as that is all that an FTA unit can get unless it has a card slot and you can use a DirecTV or Dish network card in it. Otherwise there is ways of "hacking" the receiver but that is illegal and against the bar rules I believe.
