My perants what to buy a HD RPTV and the sales person that they always go recomended the Hitachi 46f500. I know very litle about RPTVs and my father knows even less then i do. so i would like to know if anyone has any opinions on the Quality of this tv or hitatchi tv's in general. I understand that people don't like the upconversion of all signals to 540p. Any help would be greatly appreciated.
