I chose the 65GT30 and was not planning on doing a calibration. I figured I would just use THX or the setting listed in the forum. Well, i just felt the tv had more potential. Thanks to D-Nice for unlocking the potential. He calibrated THX for daytime and 3D, and then Custom was nighttime mode. I also do not use all the HDMI either. I have a Panny Soundbar with ARC. To get 5.1 from my BD, ATV3 and FiOS box, I run everything to an HDMI switch, that does 3D of course, and then route one HDMI to the tv ARC port. In retrospect, I should of bought the 65ST30 and had it calibrated. The extra money I spent on the GT would of covered the cost of the calibration. Yes, the GT has a better appearance, but that was not a factor for me. I sit about 12-14 feet away from my tv and use the SainSonic glasses. Much farther away, and the glasses do ot work. They cost a lot less than Panny's and I have had a very good viewing experience with them. So, if you get it calibrated, I would by the 65ST30 and use the extra money for the calibration and the generic glasses. Just my thoughts and YMMV.
