They charge you monthly to rent their equipment, around $5 a receiver last I saw.
Dont remember what i paid for my HD Receiver, maybe $400, but over 15 yrs it would have cost me around $900 to rent. If you switch back and forth between dish and direct it doesnt make sense to own, but has worked for me. I did finally add their insurance to mine, so if it fails they will replace it free, think that was $4 month, so cutting into my savings some. I have done all my own installs, need to move the dish again, trees starting to block it some.
