I am in the market for Panasonic TH-50PH9UK 50" Plasma TV. I have been reading expert reviews and that has been useful to me. It may be help you too. I had been using PCWorld.com, cnet.com to find reviews. Yesterday I used PriceGrabber’s expert review tab ( http://www.pricegrabber.com/info_expertreviews.php/masterid=22919626 )
and found a site ( http://www.smartratings.com ) that aggregates expert reviews. It only covers a few categories but it is pretty neat. Just my $.02.
