I just wanted to tell everyone how happy I am with Gregg's ISF calibration services. He was just at my place this evening and worked his magic on my Toshiba 57HX81. He spent almost four hours at my home making sure the set's picture was as perfect as could be. He's enthusiastic, a real professional, and is also a great guy to deal with! Once he left, I sat up as long as possible to watch various discs and some HD broadcasts. Please contact him if you are interested in getting the most out of your set. You won't be sorry. He comes very highly recommended!
