I didn't see that they said it was non-profit, and besides, non-profit does not mean "no one gets paid". Compare the sale price of any modular synthesizer with a comparable number of gozintas and gozoutas to this and it looks only a little expensive. I'd guess Behringer could make one and sell it for about $300 give or take, but they have a lot more experience in product engineering, and buy in much higher volumes than I would expect these guys to.

You could build a lot of hardwired op-amp circuits dead-bug style for $500, though, and have money left over for a base model Rigol scope and a no-name linear bench supply.

Because I should not have to pay VAT
