Hello, I am on the hunt for a Plasma tv in the near future and have been reading this forum for a while now. Recently on the internet somewhere I seen a Panasonic model TH-42PX500 mentioned. I cant find any threads about it in this forum so am confused as to what this model is? Is it an american model version of the pv500 that most people seem to have here or is it a new model that isnt out in the UK yet? Thanks in advance.
