Both publishers allow you to order on-line, so my guess is you can get them:

Hungarian book:

German book:

I own both of them; for the Hungarian one Karoly Balogh ordered a few copies, then sent them to the other members of the team. Since he lives in Hungary this made things easy. The publisher of the German book knows Michael van Canneyt very well, and they sent him & Florian a few copies for free.
