A beautiful Sobell 10 string cittern/bouzouki was donated this past year
to ZoukFest. The instrument has been posted for sale at the Mandolin
Cafe classifieds. Stefan is still not taking new orders, as far as I
know, but current price if you were able to get one would be $8,300.
I've seen this instrument and it is in pristine condition. Best offer
over $6,500 will get it--and the money goes for a good cause.
Here is the link. If it doesn't work, just go to Mandolin Cafe and you
can find it easily.
