Here are some of my frame drums I have picked up during my travels:
Tar and bendir frame drums from Kuwait and Morocco
Mazhar from Egypt
Kanjira from India
Cooperman/Velez Tar, Bendir and Mediterrasian Tambourine from USA
Daf from Bahrain
I believe that kit drummers benefit and develop when they play other types of drums (e.g. hand drums and frame drums for example). Frame drums are nice and relatively quiet instruments to play.
