Avoid at all costs.... a very old set as stated before. With sony you need to minus about £150 and then compare the new price with similar priced sets. You will then find comparable features and quality. In other words you need to minus the needless 'Sony Premium'.
For example, roughly speaking, a Sony going for £750 will be the equivalent of another Top make such as Panasonic or Samsungs going for about £600.
