The only internet published price I have seen for a new Dammann was US $35,000 and the seller claimed that he was the cheapest in the US. I have never seen a price for a used one but at a dealer I would imagine something between $20k and $35K. (Just guesses) From what I have read his waiting list is 10 years and likely closed in any case.
Dammann's postal address and phone number is on this page: http://www.focus-gitarre.de/firmen/bran ... topmenu=11
(8th entry on the list). He apparently doesn't have a website but he doesn't need one. If you write to him at that address maybe he can tell you the names of his dealers who are getting guitars in the next year or two. I think that is the best chance of locating a new one in a reasonable period of time.
Trilogy guitars in your screenshot might know if one was for sale anywhere in the US. Siccas guitar dealer in Germany might also have information as they are well connected. There are also some dealers in she UK who might have some information.
The is a French dealer who suggests that the German maker Reza Safavian who they represent has a fairly similar sound to Dammann. Here is an example. https://www.youtube.com/watch?v=riZH9fnA54I
I don't know if the sample tells anything very much. It will clearly be much cheaper than a Dammann and with the advantage that is is immediately available.
I have no personal knowledge of any of the makers so this is just internet research.
