Ivan,
Why be so dismissive? It's great that there are so many modules to choose from, nowadays. While the old Moog VCOs were not intentionally unstable, the fact remains that they have a distinct sound. Personally, I am not interested in duplicating that sound -- certainly not to the extent of getting unstable VCOs -- but I understand that some people are.
