DishNetwork 811 HD receiver


I would like to hear from any DishNetwork users that have switched up to the Dish 811 HD receiver; I have just purchased a HDTV ready TV and I am curious if I can improve my signal by going to this receiver.

I own the 811 and i am very happy with it. I do live in a major metropolitan area where OTA (off the air) HD signals are easy to get and, while the can get the OTA signal I am still happier with the Zenith HD receiver that I had before the 811 so I use the 811 for satellite and the Zenith for local broadcasts.

For more info on the 921, 811, etc. go to www.dbstalk.com

(while there, check out the 'laughter is the best medicine forum'......
...I just found out about the model 921, that is the one I now realize I would be interested in. But, either way, anyone with experience with either.
