Hey Tom, I had both at the same time too, and now I have only one. And its not DirecTV. It all depends on your signal quality--I had SAT A, B, and C in the high 80s to high 90s and I still get better PQ from Comcast. YMMV.
OTA is free, and that is a *good* thing, in the words of a notable convict. If you bought your set now, it probably doesn't have an OTA tuner--buying one will set you back a couple hundred on an open box special. I'll second UncleJeff's recommendation of antennaweb.org. It will tell you who is on air in your area and what kind of antenna you need to pick them up.
