Hello Ti Dor!

Right now we’re preparing for crowdfunding campaign, you can subscribe here: https://www.crowdsupply.com/virt2real/stereopi

We plan to start it in a several days.

As for prototypes — we can sell you one, but they are more expensive because of a small batch quantity (approx. 3 times more expensive). It is better to wait for crowdfunding and batch production to buy one with a normal price. But if you insist on buying — you can contact me by email info[at]stereopi[dot]com
