My trusty Panasonic TH-42PX70P has just packed in. After reading hundreds of reviews etc etc I've narrowed it down to either the Sony KDL-50W829 or the Panasonic TX-50AS650B. I'm on the verge of parting with my cash (sometime next week) so any suggestions to which is the better of the two ? or even throw me a curved ball and suggest a different TV (for under £1000).
