Toshiba Sony Hitachi Panasonic Am looking to purchase a RPTV, between 42" and 50". Not bothered about onboard sound, since I have separates. Tosh's seem to get good reviews, but is the Progressive Scan on the Hitachi worth having? I would watch DVDs, digital TV (Sky Digital) and analogue TV of course. Please post if you own any of these models. Many thanks!
