G30 is the top 2D only then you go up to mid range 3D with the ST30, then GT30 and VT30. As Vickster says the VT is the top end set. What distance will you be sitting from the set? the GT really isn't that far off, I went for the 46" GT30 instead ov 42" VT, the differance in size is bigger than the PQ dufferance, then Im about 8ft from my screen so its worth going bigger.
