Well Gregg Lowen came by yesterday and calibrated my Samsung.The results were incredible.I will never have second thoughts again about getting a calibration,it will just be budgeted in to the next purchase.Even if it means getting less tv,because after the calibration it will be much more than the more expensive UN-calibrated set.Colors----amazing,depth of the colors----amazing,percise colors,could not be better.The black level,while acceptable before,is--with out a better word--deep.The detail of the set is now very crisp,clean.Money well spent.It was so interesting to watch every thing come together that I am going to take the ISF course that Gregg and associates teach this Feb. in NJ.Well gotta get back to watching to game on my new set.Call Gregg you won't regret it--after you see--you'll regret you didn't earlier
