I've bought the LCD recently, and the quality is good... In Sony, the picture appears less vivid as compared to Samsung... If you're someone who watches movies and videos and stuff from a portable HDD, they have a feature where u can plug in ur HDD or USB device and enjoy watching videos in over 14 formats.. Do check though if this is available for all models.

The sound quality between most LEDs is marginal...

I'd highly recommend the Samsung purely because of the better quality of video and viewing experience..

And whatever U do, Don't buy from Lulu.. I had to follow up lotsa times to get a guy install my TV.. and finally, the guy from Techno Blue came...

But still, please research a lot before U plunge in.. coz in the end, its what U want..
