so i have done the measurements in the room where my new tv will be going , on the main facing couch it is 3.50 mtr away, my on going struggle is weather or not to go and get a full hd or just plain hd ready , the tv i have in mind is the Panasonic TH-42PX80B i read alot of good reviews , but there is that niggling the fact that is not 1080p , would it be worth paying the extra for the z series , or would it be a realistic waste of a further £200 . Any feed back please.
