From a reliability point, the only standout is anything made by Panasonic. Sony has lots of bad LCD panels out of warranty, = throwaway.
LG and Samsung are built poorly, life expectancy 2-5 years.BTW, with those and other companies, the newer stuff is built far worse than the older models.
Just my $.02.
If you ask me, just about everything mass produced toady is junk! You either get a good one or a bad one! I wanna say that I have to return just about 50% of the things I buy today! However I do have two Sammy TV's both LCD. One is a Cffl backlit LNB750 and it is 2 years old and looks and runs fantastic and I just bought a new UN55D8000 and knock on wood that it is a fantastic TV so far!
