Yeah I figured they would be (works out cheaper for me so was hoping there would be a few more).
Looks like I will hunt down affordable standard copies of Doug Carn - Spirit of the New Land, and The Awakening - Hear, Sense and Feel.
Check dodax from time to time, I purchased two Black Jazz reissues for 21,99€ shipped each.
EDIT: Maiden Voyage is one of them, the other is Coral Keys.
