My parents have asked me to source them out the best 40/42" tv i can get for £500 there may be abit of flex in the budget but not much. They currently have a basic dvd and a tompson freeview twin tuner connected so a quality onboard tuner is very important, future wise i guess they could possibly have a freeview HD twin tuner and an upscaling dvd but nothing more. I was thinking about the TX-P42X20B but is there anything better about ?
