I've been in touch with someone about getting a bottom-up calibration done on my Mits 55807 by someone who many regard as THE calibrationist for Mitsubishi RPTVs. The issue is that it would cost me $750 to calibrate a set for which I paid $2750. This seems a little steep for me. The alternative would be to not get any calibration done, as the calibrationist in my area has no experience with Mits sets. Is it worth that much?
