how to select a blu-ray player ?

how to choose a blu-ray player ? You should read reviews before buying one, because everyday, a new product is coming up in the market every day with a new feature. So if you don't update yourself with the new stuff in the market, you may loose a feature though you spend the same money or even more.
I have collected the reviews for all the products that are coming into the market so that you can choose a right product.
