Lovely erhu model, Cooler. I've seen it performed in concert -- lovely sound. One note; the bow string, unusual to fiddle-type instruments, passes BETWEEN the strings. Koto might do you as a stand-in for the zither family. I have not seen a koto yet but the guys and gals at Expanding Wave were supposed to have one, and a full set of Gankaku instruments, in their new store.
