Yep,,, had my Sony XBR calibrated twice from a tech in the Boston area. Cost me $375 each time to have him drive to Rutland, Vermont and for me,,, it was worth it!

I contacted Jim Doolittle of Waltham, Ma., he comes highly recommended and has even been featured in Sound & Vision. Whatever you do, find a tech with a color analyzer. You won't have a calibrated gray scale w/o it.

I would wait til the set is at least 3 months old so it has had a chance to burn in. I have my set calibrated every 2-3 years.
I would also suggest Ideal- Lume from CinemaQuest for 6500K background lighting for your display device. The gray scale is set at 6500k and having a white light background will accentuate the colors while creating less stress on your eyes.
Good luck!
