Those who know this site like the back of their hand will know that an earlier thread regarding ISF calibration, brought out the sceptic in me, and that I thought the price was rather high esp as there is no silver boxes to how for the money!! Piers has just left my home after calibrating my system, and the price seems good value! Everything looks more natural, DVD is even better and sky has been cleaned up a bit. Anyone who wants to get the best out of their screen can not do better than an ISF calibration by Piers. The results were outstanding, and Piers is a knowledgeable, and thoroughly decent man. All I can say to him is thank you.
