I am looking to buy a affordable but quality HDTV.I have been to Circuit City and Best Buy and have gotten confusing info on HD tubes vs. HD projections. For instance a salesmen told me the Sony Wega HDTV is only 480 and not as good of a picture as a LCD Sony rear projection HDTV that has 720. Is this true? I always thought tubes were the best for picture accuracy. Does the Sony Wega Trinitron 34'' HDTV have as good of a HD picture compared to other high end HD flatscreens?
