I wish I knew when DishNet was going to get local HD. But as long as I have my locals OTA I am not to worried about it.
When I was doing the reasearch before I decided on DishNet, I looked at Comcast (who I have for internet), Directtv, and DishNet. At that time DishNet flat out had more HD programing than any of them, which is why I chose DishNet. Now I don't know, but I think that I am going to stay with them mostly due to their award winning DVR, I have the ViP622 and most likely will upgrade to the 722 soon.
As far as OTA stations, I currently am using an antenna that i got from Monoprice, and I am receiving all of the stations, plus ones that I don't care to watch. I live out in Reedley, and this antenna is both UHF and VHF and cost much less than $40. The only station that I get random is the CW which I do not watch often. Oh, I have it up on the roof. OTA HDTV looks awesome! Followed by the good DishNet HD channels.
