Watch out for that cheapo plasma TV from Gateway. I use 'cheapo' in the "relative to other plasma tvs" sense here.
I have a Sampo 42" plasma (which AFAIK is what the Gateway is) which for the most part is really cool, but there are some drawbacks.
It has trouble with very dark scenes which causes patches of single colors to appear as it struggles to figure out what shade of grey/black/brown to display.
The fan is really noisy for quiet scenes.
It is only 480P and has to fit higher resolutions into that screen size.
All of this is not a problem if you are not worried about HDTV as 480P is fine for DVDs.
Since I could not afford the extra $2000 needed to buy a Panasonic or a Sony, I can live with these problems and enjoy my really nice wall mounted TV
