Are these being sold as PCBs only or is there a way to get a fully assembled board?
Kits only. They provided all the parts as a package if you wanted, or, you could source them yourself. I chose the former. Now, it's off to Acill to assemble it for me.
and pay with an international bank transfer... I tried to order two and it didn't work out 
Congrats to everyone that did get one! What a board for the Vampire!
I paid them via Paypal. I asked very nicely, auf Deutsch...

You had to have been a member of A1k website and be able to read German to get one. 
Or use Chrome with automatic translate turned on
