Could anyone tell me how much it would cost me to cancel service on a Choice Extra package with HR21-100 DVR 1 yr into the contract? I'm having tree issues and i'm afraid it would be cost prohibitive to cut down 2 giant oak trees. My dish is already mounted on the crest of my roof so I don't really have any more options. My back yard, which faces south, slopes uphill and is full of big trees.
