I have recently tried to buy a Panasonic TH42PZ70 from a well known internet company. They have had my £840 since the start of Jan. They are now saying that the model is discontinued and they are unable to supply. They are offering either a TH42PZ80 in April with a 3 yr warrent or a TH42PZ85 in March which they claim is an upgrade. Should I wait for a TV that I have only seen on the america web site? Or can anyone recommend a similar standard replacement or should I get my monies back.
