Not to reopen a can of worms, but Digibase CR200 is not a viable option unless you want an unpredictable "alternative" look. The more I've used it, the more I've noticed variations in the heaviness of the color cast and the effective ASA. It's grossly misrepresented by the vendors that sell it. I happen to love it though, and I'll continue to use it as long as it's around.
