We're considering the addition of a color grading suite here at our studio. The Final Touch 2K system is, so far the front runner. I want to keep our workflow on OS X and so far that's really the only way to go. I also looked at the Iridas SpeedGrade system but the Final Touch system priced out to be less than the SpeedGrade software. It'll be interesting to see how this segment of the post market grows.
