47LH40 I have loved my television since I purchased it in early 2010. The picture is great and I have not had any problems with any of the functionality or connectivity. I have it paired with the LBH975 surround sound system and it works flawlessly. This version doesn't come with the internet connectivity, but the surround system does, so everything I could want to do with my setup is available to me and it all functions great! I would give the TV a straight five stars except for the fact that it is getting older now. That being said, I am completely pleased with the LG products in my home and would definitely recommend them to anyone who is looking. October 29, 2011
LG for sure This TV has the best picture I have ever seen, you watch movies and sports and this TV delivers and its quality is way better than most TVs that cost twice as must. Anyone who does not have this TV in their possesion is missing out. October 29, 2011
