Re: 3D Plasma or LCD LED
I just picked up a 50" Samsung 7000. The TV itself is outstanding. Colors and blacks are much better than my other Samsung 550. The 3D so far is kind of ho hum, but my only examples come from Directv's one 3D preview channel.
*update* Just looked at some 3D movie previews streamed online through the TV and it looked far superior to what Directv was showing.
