I was thinking on buying the 50"er but I noticed it does not have a built in HD tuner. How big of deal really is this, if most viewing is STD cable and some DVD's? Oh yeah and some PS2/gamecube. How much are the tuners for this TV? I have seen them from $42-$600. Any other LCD's screens out there 45" - 50" under $3000? The panny, not sure if I like the speakers on the side. What about LCD realiablity? Buy an extended warranty?
