What do you think about Behringer who announced a re/issue of the CZ-1 as a small module. I personally have many of the replicas that Behringer made of old synthesizers and I love them dearly. Finally I can aford the synths of the 70s and 80s that were unreachable for me at that time. Of course a lot of them are monophonic analog machines which have a rich UI with one knob per function, but I also like the digital ones like the Brains or Victor which are much harder to program, but still have a very easy to use UI. Same is true for Korg with their volca line. The Volce FM is just great, even though I have to program the DX7 sound on a PC.
