Welcome to SatelliteGuys @3dr1.
What kind of FTA are you after?
You also mention OTA, which usually refers to terrestrial signals via a standard TV antenna.
Are you wanting OTA also, or just FTA via Satellite. You can find sub $100 dollar boxes on eBay, I see new ones pop all the time.
Most of the time they are not "New", just same box with a different name slapped on it.
I would stay away from 99% of those though, because most have no NA support and usually are not well suited for true FTA.
