Today I received my DanLock puzzle direct from it's maker, Dan Feldman in Israel. He makes two versions of this puzzle. Mine is a type B which contains everything that the Type A has plus something extra that "makes it just slightly more difficult to solve" (according to Dan).
The puzzle cost $100 which included the airmail shipping (it took less than 1 week to arrive).
The puzzle is stamped with a serial number, mine is DLB094.
More information about it as well as how to order one can be found at http://sites.google.com/site/danlockpuzzle/
This seems like a very high quality collectible puzzle.
