I did see one of those copies, it is much cheaper but not to the same level of engineering. As you know it is the accuracy of the machining that makes it so good, the drill holes are exact and to date even with many dowels I have not had any alignment issues, a real case of you get what you pay for here and when it comes to repeated accuracy it is better than my Domino 700. I helped a guy with some issues with getting joints to close, his was a copy and the issue was that with the genuine article the holes are exact from either end of the block, on the copy they were out enough that you had to always ensure you used the same end.
