I have two Malian jeli dunun and one konkoni for sale. All of the dununs are carved out of dugura wood and the goat skins were prepared and sewn on here in Denver, CO. These instruments are rarely found outside of Bamako and offer a very rich, dynamic sound which is quite different from cow skin dununs. All drums come with the traditional dunun kala (curved stick) or konkoni kala (lightweight, pegged stick). The jeli dunun are $475 and the konkoni is $375.
Here is the link to check out the specs in more detail:
