I would say originals of Lunar Strain and Subterranean are harder to find, since a lot of people who have Black-Ash are selling it to make money.
Or if you want really rare the disc that was only available in 1998 at Colonization shows
Lol, I need to pick up some reprints. I have all of the old CDs, but their worn out from playing and shit. Heh, I have the CD covers hanging on my cube wall.
I also own Ceremonial Oath's carpet cd. And I have the original version of Dimension Zero's Penetrations from the Lost World and Ceremonial Oaths Book of Truth albums in the mail
