I think there is good and bad in Uli's business approach. Behringer's Model D took a $3500 instrument and distilled it into a $300 analog synth module. The Eurorack line based on classic designs has been uber affordable and reasonable.
Modern electronics manufacturing has been a break-through for small batch electronic instruments and devices. It's profitable for a small company to compete among large manufacturers when designing modules and devices from commonly available electronics parts. I think almost everything obscure or out of reach in the 1970's or 1980's will be revisited and made affordable if there's some profit in it.
