Has anyone tried the B&W King developing reel & tank system? It appears similar in design to the Nikkor 4x5 reel & tank (which some like, others do not). Unlike the Nikkor, one B&W King model will take 5x7 film, up to 6 at a time. The construction differs from the Nikkor in that the spiral reel ends are cast stainless, so it does not have the numerous welds that the Nikkor required to manufacture.

Thank you.
