I need to purchase an RGB/YUV (component) converter to connect my Sky+ box to my 42PMA400E plasma screen via my Denon AVR 3803 amp. I'm using S video at the moment which is not optimising picture quality. The JS converter looks the best but it is priced at £145. I've also seen one from Letropacks for half the price (£75). Does any body know if I am going to get noticeably better results from the JS converter? I don't want to 'spoil the ship for a haporth of tar' but I've already spent a fortune!
