Just about any LFS will sell them, most people will grow them. From Vancouver talk to these Zoa horders:
Justin (canreef ID - jjntm) - HIGH end, top quality stuff. Don't know if he ships though.
Dave (AcePumping) - LOTS of frags and colonies
(Din Gior) - Always lots of nice stuff in his posts
I have a few (see
here), but not as many as these guys.
Good Luck!
