I recently bought the Sony W550 - 40 inches.
Amazing clarity. Absolutely delighted with it.
I also have a Samsung 5 series 32" in another room - not fully happy as there is loss of pixel as one nears the TV - did not feel it with the W series even at a distance of 3 feet (using Tata Sky in both TVs).
I had also checked the Samsung LED series - but found the images to be too soft (leave alone being pricey).
