I just dropped Gregg off at the airport after having my Tosh 50H81 calibrated. For those of you out there who are wavering over whether to get it done, or if it will be worth the money, I am here to tell you to GO FOR IT! It is the best money I have spent on my set. The difference in viewing it out of the box and after Gregg tweaked it is nothing short of astounding. I am seeing detail that was just not there before. There are intricacies buried in the shadows that were not visible before. I cannot recommend his work highly enough, and it is not just because Gregg is a nice guy. It is because he obviously knows what he is doing. Stop what you are doing right now and go to Gregg's site at www.greggloewen.com and sign up for a calibration. Don't think twice about it. You will thank me and thank Gregg when he gets done, I assure you! Timothy P.S. Thanks, Gregg!!!!!
