My Hanzo is a very well built device, and I have had no issues with my cable (apart from it being very short); it seems to be very high quality, but it differs from the current images on their web site (I assume they must have changed the cable design or supplier, for some reason).
At any rate, appearance aside, it will be interesting to see how this CMVS compares to the other options out there. I only have an MV-1F and a supergun, and have been considering either making or buying a CMVS. Pretty much any of the options out there would be a much cleaner solution than anything I could make, I'm sure.
