What about the Dark Detailer and the ISFccc features? Do those matter much? I'm considering these two TVs also, and have a few calibrations discs so I know a bit about that, and I've had some of my past TV professionally done. I don't what Mits does with the Dark Detailer, but I've heard about how some DLP TV's have a better iris to handle shifting light levels. If that's what it is, I'd hate to give it up.
