I am looking at buying a 51" or 52" HDTV. It will be hooked to an antenna. (no cable or dish) I've narrowed my search down to three tv's in the $1000 price range. They are Magnavox 51MP392 H, RCA D52W19, and RCA D52W25. The store reps all tell me that each one will work on my antenna connection. Has anyone out there had any experience with any of these models ? I'd appreciate your input. Thanks ! DWE
