Got the 50v20d for Rs. 97,000 from Delhi. I will always prefer to go for a flat panel that comes with 3 year warranty than the one that comes with the standard 1 year warranty. I have been on the receiving end in my past purchases of samsung flat panel T.Vs and LCD monitor so will strongly caution anyone against samsung. You can read all about my ordeal here. Also note that the after sales service of samsung is unimaginably poor. They listen to the customer only if consumer court case is filed against the company.
I have not used any burn-in images with v20d.
Which store did your buy it from? I've been looking for 50v20d at a good bargain but no dealer drops below 1.17 lacs!!
