From what I understand dragonbox.de put up new GCW Zero units but they got sold out pretty instantly, so I definitely think the market exists for it if you are willing to ship to Europe. I wanted to get one from dragonbox but alas, I was too late.
So now I've preordered from you, using a US-resender service to get it sent to Europe.
(it would be nice if I could buy it directly though, then I might even buy two of 'em)
