Hi, I haven't seen much discussion around calibration on this forum in quite some time. Is it still recommended to do a professional calibration for new plasma TVs? I've ordered a Panasonic Viera TC-P50G25, and want to make sure I'm getting the most out of it. Also, are people still generally thumbs down on Best Buy's Geek Squad doing calibrations? That was the consensus, but the last post was almost 18 months ago. Thanks!
