I got one of these, a few weeks back. They're quite good, at least for HD and/or upscaled viewing. The TV's own upscaling is not too great however, but depending upon how far away you sit, it may not bother you. The built-in Freeview is fairly decent too. Personally, I find the SD quality to be good enough for the distance that I sit from the set, which actually isn't that far away. Overall, I'm generally quite happy with this TV.
A warning however, a lot of people, including myself, have noticed a brightness strobing issue on this set and from what I've read, also seems to be present on most current generation Pansonic sets. The issue effects certain scenes/images, whereby a bright colour eg. light grey or white, or light blue etc in the background, but a dark black/grey image in the foreground - the lighter background will flicker/strobe. Not always visible, some movies/TV shows etc are affected more than others. It will either annoy you, or may not even be visible at all. If you're an absolute picture quality purist, then probably best to avoid this, otherwise ignore the potential issue and go ahead and get one!
