If you are planning on using DirecTV, inexpensive is not the word to use.
It all depends on how far from the OTH main antenna you are.
Research that first before you cut the cable.
A DirecTV solution could easily cost 2x more than you are already paying.
Paying only 60 bucks/month for my DirecTV HD with DVR service. Not the barebones, either, but no premiums. Threaten them that you're leaving for the competition, they'll drop the price. What do you mean by distance from OTH main antenna, and how that would affect pricing?
