Got the 50" samsumg 3d from bb for $490.
Are you talking about this: (or something along these lines?) http://www.bestbuy.c...6&skuId=2135072
Your comparing a 51" 720P Samsung Plasma (that is outdated and very low end) passive 3d display.
The 24" is 1080p ACTIVE 3D Display WITH active 3D glasses (which will retail for $70), includes TWO games (which will probably be retail $80 - 100 around the release of this TV), and an HDMI cable.
So lets say:
Playstation 3D Display 24" - $330 - $350ish
Resistance 3 - $50 or $60
Motorstorm - $20 or $30
3D Glasses - $70
HDMI Cable - $10
For those unfamiliar with the difference between active and passive:
Passive 3D essentially splits the resolution of the 3d images in half, and uses two different lenses.
Active 3D, on the other hand, has technology in the glasses, and keeps full resolution of the 3D image on screen. The glasses repeatedly blink back and forth (very very fast) to give you a full resolution 3D image.
More tv's now a days are using Passive since it's cheaper, but Active is truly the best for quality.
I personally have no intentions on buying a 3D TV, although i cannot deny this a a great deal for an active 3d television.
