I have noticed sevel threads about the Panasonic 500 series and it is getting a little difficult to keep a track on them. Please could people post their comments and finding about this exciting new plasma on this thread. Please could people post information on the PQ, HD, SD, and information on extended guarantees. I have read comments that Panasonic shops are giving away 5 year guarantees free of charge for this model. Would really like to know if this is only exclusive to Panny shops or is it model specific.
