bestbang4thebuck,
i happen to see a live and working LED samsung at 54". it was showing a HD brodcast of a college football game.
in a word: WOW!. Then the source material was switched over to a NASCAR race. I wish i had a cold one. I was ready to watch the entire race and i'm not much of a race fan.

BloggingITguy,
Have you checked out a properly set up HP DLP at 65"? ssaaweeeet. And yes i have seen a sony SXRD.
And the motion artifact will probably disappear.... considering the mirrors dither extreamly fast.

From the stuff i have been hearing/reading - there are some cool things happening in DLP.
