DLP's are that great honestly. the picture is better than most lcd projection tv's cept for the sony's. But you still cant see it from any angle. The best projection for side viewing is still a sony but its still nowhere near as good as a plasma or lcd.

dlp is nice for its bulb to be easily changed, and cheaper than the sony ones.

but yeah nearly every plasma has a way prevent burn in. it doesnt work 100% but it takes longer for this to happen. they all also have screen savers, basically a full white screen you gotta run for 8 hours or a shifting white to black screen but both do the same thing.
