We have an 8 year old TV in our motorhome and it's dieing a slow death. Considering replacing it with an LCD flat screen. We use cable or satellite for our source. Since satellite is a digital signal, does that mean my old set is receiving/displaying digital? And there are so many LCD sets out there I'm getting confused. How important is it to get one that has integrated HD? My old satellite receiver probably doesn't receive HD...ya think? Getting a cable company STB is not a good option since we change locations several times a year. Would I be just as well off by getting a good LCD digital set and forget HD??
