Sony Bravia KDL-42W650 is still not very popular around the world and the reason for that is not the lack of quality or functions which this TV is fully packed with but because of the fact that the  KDL-42W650/ KDL-42W650A is mostly going to be sold in Eastern Europe and some parts of Asia. Of course you can find this TV in other countries as well but it is still not presented in huge markets like UK and USA.
