The McGregor run is also available as a Marvel Masterworks HC:

Actually, the prices listed are quite cheap for a Masterworks. If I didn't own it already, I'd lock that down.
The great things about the Masterworks volume, besides the color and better paper, are a lengthy and informative introduction by McGregor about what he and Billy Graham were trying to achieve with the series and a beautiful afterword by the late Dwayne McDuffie on what it meant to finally have a superhero that looked like him. Both are essential reading for tracking the evolution of depictions of diversity in the history of comics.
