Just my 2 cents, but I had Chad Billheimer drop by to do an ISF calibration on my 71 series Samsung and JVC RS1x last week. I've used him before as I've mentioned in an earlier thread, and will continue to highly recommend him. He's friendly (i.e. answers my noob questions), takes his time, and is very detailed. I had done the DVE stuff on Blu-ray which is reasonable but without the proper equipment I couldn't do the full treatment. If you've got the scratch, haven't got the proper equipment, and want the best picture you can get out of your display, consider giving Chad a try if you live in his service area. Incidentally, I did try to reach several other calibrators via some really nice web pages but have not heard back from any of them (after a month), and Chad in that same time has come, done the job, and now I'm back to watching movies.
