Well, I'm going to disagree about your reprocess Greg - I think you've gone far too soft!
Looking again at your first attempt (which I believe is still your thumbnail attached to this thread), I now think it's overdone. I had thought my image could use some more contrast, especially on the ridges in the nebulosity, but after seeing your repro, I'm more satisfied with mine.
Maybe somewhere in between??? I really think you need to pony-up and try Pixinsight - HDRMultiscaleTransform does a fantastic job of compressing the dynamic range. Works wonders on giving a 3d feel to these "flat" areas on nebulosity
