Thanks! I tried the JC profile as well and it was a bit dark. But the main problem with all of the profiles I tried from the board was the cyan cast. They all just seemed a bit bluish or greenish. That's what prompted me to just pony up for the Spyder3Elite.
I have to say, the process was amazingly simple. In about 20 minutes, I had a working profile. I calibrated three times but could distinguish no differences between the attempts.
I like this one because it gives a warmer cast to the white without being too red. There is another profile out there that is simply way too warm, at least on my display. The warm white looks best, especially when combined with a 2.2 gamma.
