I'm not darkshadow but from everything I've read image burn hasn't been mentioned once in reviews of any of the newer model plasma or LCD tvs, even the sub-$1000US versions.

The response time of that Samsung is low at 4ms, but they stated the input lag occurred with PC inputs. Since a console is basically a PC, I'd imagine it would have the same problem, unless you connect through a HDMI or maybe a DVI cable. Maybe the issue only occurs with 15-pin VGA connections?
