> Those synths are famous and expensive because they're an important part of musical culture

Not only that, many synths are expensive at launch because of R&D and production costs (considering the small amount they produce), and impossible they're already part of "musical culture" as they just launched. TE and Elektron stuff is expensive at launch as just one counter-example.

But Teenage Engineering or Elektron are putting out original creative stuff. Even if it is built around vintage components like the SidStation (which is still one of the devices I really regret having sold)
