This is not going to be the greatest piece of help I've ever been able to give anyone. However, if they're still available, these two discs have examples of Ukrainian bandura players:-

Musiques Traditionelles D'Ukraine 1-Steppe-Carpathes-Podolie Occidentale-Boikivchtchena. Silex. Y 225211
Musiques Traditionelles D'Ukraine 2-Polesie-Poltava-Kiev. Silex        Y 225216

Also, check

http://en.wikipedia.org/wiki/Bandura which has some info about the bandura.
