I am not a collector of every last Fab artifact by any means, but my opinion is that there are 2 options: For relatively completeness's sake--a 3-disc edition identified as BATZ 0053-0055. For slightly improved listenability--albeit much hissier--a 2-disc set called "Zu Laut!" from the good folks at Mobilephone.
Bizarrely, I own a truncated CD edition issued by K-Tel USA back in 1986. It laughingly includes "Hully Gully" which wasn't performed by them!
That's about all I can say. The "experts" at the Hoffman forum live for this stuff and go into an astonishing level of scrutiny of the tapes, with only occasional lapses into pedantry.
