I've just ordered and paid for a Sony KDL 50W829 (I was expecting the BBU model) but Argos have gone and delivered the Sony KDL50W805C by mistake. My question is am I better off? Is the W805C a match for the W829b? I spent a lot of time deciding on the W829. Please could someone shed a little light on the difference between the models and maybe offer a little advice if they have any? Thanks chaps.
