Aztec just issued a 4 CD set of everything issued on the Go label, which covers '65 to '67.

Nothing trippy here, but a lot of solid Aussie beat and many of the original 45s on the label now go for some serious money when they do turn up.

This set is very reasonably priced and with postage, it amounted to less than $50 US.
