Has anyone here ever seen or used the Jobo ULF film drums. The Adorama website lists these as the Jobo 3027 (for 11x14), and the 3028 (for 16x20). These seem to be no longer available new. Know where I can find one or two? Secondly, I sure would appreciate hearing comments from anyone who has done dip 'n' dunk processing of 11x14" film. What were some of your difficulties? What equipment did you use? Any hints or tips? If you did several sheets at once, how did you wash them adequately without scrathing them? Thanks for any input.
