The wait is long because Colin won’t let units out unless they are 100%. That’s lots of work and there is a fairly small team qualified to do it right. He’s not trying to piss people off, just refuses to cut corners.
Units do appear second hand if you are at your wits end but I would hold out to get one direct if you can.
It’s a brilliant box, not for everyone perhaps but I would jump straight back on the waiting list if mine got stolen.
