I can buy the HD700r from here if needed.

Also how do I know if the sub channel is broadcasting in 1080i or 720p and do I need an amplifiers? Its strange that you brought up HTPC's I actually plan on using the HDHOMERUN Dual in conjunction with Windows 7 Media Center. Also whatever antenna I get I do not want it to be seen from the street. As of right now you would not even know that we even have a dish until you enter our backyard. Also I spoke to a rep at our local abc station he told me that if I pull WABM-DT 68.1 than I should be able to get all ABC and all of it's sub channels since they come off the same tower.
