I have decided to take the plunge into plasma. This will be for home use. Panasonic seems to have generally high marks. Does anyone know if there are any differences between the Panasonic TH-42PW4B and TH-42PWD4 apart from the charcoal frame, the amplifier and the price? Is there anything else i should know? Have any better plasma screens been introduced recently in the same price range? Suggestions gratefully received.
