One cool thing is that after The Legacy of Thanos is released this summer, nearly the entirity of Roger's run on Avengers will be back in print. You'll have:
Absolute Vision, vol. 1-2
The Legacy of Thanos
The Once and Future Knag
Under Siege
Assault on Olympus
Heavy Metal
I'm really happy that I'll have all of these on my bookshelf to re-read anytime I want.
