Just scheduled my long awaited calibration for my Hitachi 57f59 for Wed. Jan 23rd with a company called Lion AV. I must say as far as customer service and scheduling go, I am very pleased so far. I started by going to their website and booking a calibration, I was then promptly contacted and able to schedule the calibration during one of my days off. Gregg Lowen, who will perform my service, was very mannerable and gave me specific instructions in which to prepare ("cut out" my ambient light). His testimonials seem to hold him at high regard. I'll post my comments after the service along with a before and after pic.
