Hi,was looking for some advice on buying a new telly,I currently have 4 shortlisted,they are,Sony kdl37ex503,Sony kdl40ex503,Samsung le37c580,Samsung le40c650.I can get the Sony`s for £500/600 respectively and the Samsungs for £429/600 respectively.My new tv would be used for blu ray playback,freeview hd and streaming movies so wifi would be necessary,I know I`d have to buy the necessary dongle for this.Wpuld really appreciate any advice as this will be the last tv I buy for years hopefully.Thanks guys.
