Most pieces on my site can be ordered from the publishers. Some of them (including the Bohme piece) are listed in the Spaeth-Schmid guide:

They also have some arrangements by Gyorgy Geiger. The original compositions by the Hungarian composers (From the Gyorgy Geiger CD, you should really get those!!!) is not in print. I got copies of the music from Mate Hollos, who is one of the composers and also the director of Hungaroton.
If you sent me your address in a private email, I can sent you something.
