I do not believe that they are importing them in the U.S.A. yet.
I , like you, have been trying to get one for some time.
They are hugely popular in Europe -- in Germany & Italy particularly (my research has found) they are favorite guns for IPSC competitive shooting.
I found out from the BUL Israel website - the following information that might help you:

They are rare in USA right now - Most of of the one's I found (a grand total of 3 in searching for about 18 months) were brought into the country by people who worked overseas and brought them back with them
Good luck in your search.
