That series is good and cheap. I have most of the reissued titles in other formats (i.e., Polydor UK, Fontana, Spiegeli, Black Lion, etc.) but you could get in the door cheap with Arista-Freedom. I think Cadence used to have them for $1.99 or $1.49 in their catalog back in the late 80s, well before I knew there was jazz other than Miles and Coltrane.
