I am in an area served by USDTV.
There website lists a few channels in SDTV.
Not really sure if this is a good option.
I think the PQ would be better then Dish or Direct TV.
I get NBC, ABC, CBS, PBS (actually 2 HD stations, and 9 SD PBS stations), Fox, and WB in HD off an OTA antenna.
USDTV lists ESPN, ESPN2, lifetime, Food Network, and a few others for my area. However, the channels list says these are in SD.
Not sure if this is worth looking into or not.
