Well either you can go with HX750 now if you are okay with Active 3D. Or you could wait a month and go for Bravia W802A (HX750 successor) with Passive 3D and X-Reality PRO chip.
Well whats done is done. So whats the price for which you are getting 40-inch HX750? Is there any significant difference in price as compared to LM6400?
I have already stretched my budget for HX750 and I'm not in a situation to shell extra for HX850. I'm getting HX750 for 71K. I hope it is a good price compared to market price.
LM6400 was offered for 67K. With this model there is an offer of free 3D BDP and 6 glasses. With Sony I think there are only two glasses free. Getting additional glass is also expensive when compared to LG. I liked the Cinema Screen design of LG with the narrow bezel and the 3D was excellent. Actually I was thinking about a 2D TV and it is then I watched this LG 3D and I changed my decision immediately to buy 3D TV.
