Hi, I have been on a lease with Dish since 6/7/05. I have 2 811's and I'm not happy with the PQ on either. I also don't care about HD at this time. Dish is willing to swap out the 2 811's for 2 510's at no charge-installation is included. They also are putting on a $60 credit to defray the 1st year fee on the DVR. I have not had a DVR. Can some of you tell me how you like DVR's, and the 510 unit. Thanks.
