I emailed asking if they have an expected dispatch date yet and got a quick reply.
No dispatch date yet, but was told I'm now fourth in the production queue. Though I have no knowledge what that means in terms of time. If they make 50 a year then it is four weeks away from production, but that is just a guess.
I did also ask about tools for regulating the controller, I don't want to have wait for another delivery from the US to make any adjustments if any are needed after delivery. So I need to make up my mind on what to get.
