My only concern about DeGroffs is that they are large and heavy and extend out far on a thin metal tube. One of my cameras has a small cup hook screwed into the top of the lens board frame, and I assume that was for hooking the air tube through. It helps me believe that I won't pull my shutter apart by accident some day. And you are right--the DeGroff makes those with the tiny black tubes that reel up on a reel seem like trash.
