Hard as it may be to believe, there's a difference between things that don't interest you personally and things that are junk. And the existence of things that don't interest you somewhere does not automatically mean that everything there is crap.

Don't see the sort of kits you like being made? Join us! Innovate, and design your own!

I'll give you the last item, but the rest are junk. Sorry.

I would rather, for music, use http://www.paia.com/ or http://www.doepfer.de/ for example.

Doepfer are well outside the price range of experimenters.

Some of their analogue kits are eye-wateringly expensive for what they are.
