I love my 58' Panasonic S1 and from what I can remember the 46" version is exactly the same quality. I think Panasonic is the only company doing Plasma justice right now and IMO it looks better than LCD and if you are worried about burn in, don't be. My son plays his Xbox on it for hours at a time and I have had no issues what so ever, not even a little image retention.
