First of all, I request you not to use SMS text language. This is not as per forum etiquette.
All I can say that, do not buy any TV because of 3D. Consider that as a bonus feature. Trust me, even if you are a 3D crazy dude, you will not watch 3D for more than 20% of your time; and I am being very generous here. Why?
- Because there is very little 3D content as of today
- Because to download a 3D half-SBS movie (typically 15 GB), you will take ages
- Because 3D is tiring to watch, even passive 3D for that matter.
- Because 3D TV (as well as Cinema) is not natural and anything unnatural is not good.
- Because 3D as a technology is still evolving
Concentrate on the best PQ that your budget can offer.
That said, I was not very much impressed by LM6690 also. And I was looking at the 46" (because the bigger it is, the better the 3D experience). At 124k or so (don't remember exact price quoted), it was appearing overpriced also. Hence even though I prefer passive 3D, I went for plasma because of PQ.
