In the 1990s, I used a JOBO processor and drums to process B&W and E6. The water bath was essential for E6, and nice to use for B&W processing. Around the year 2000, had my E6 processed by a professional lab. MF B&W film processing preferred to use Kindermann metal reels and tanks. LF B&W film, tray processed.
Come a few years ago, I was shooting a lot more LF and ULF B&W film, so I got a CPA-2 and their tanks for 4x5, 8x10, and 11x14 film. Built a new darkroom and placed the CPA-2 on a traveling cart which was storred outside the darkroom. When I was processing LF & ULF B&W film, just rolled the cart into the darkroom, filled the water bath with water, and when everything came up to temp. processed the film. Drained the JOBO, repacked up everything and pushed the cart outside the darkroom. Honestly tray processing the film took a lot less time and effort.
Last year acquired 2 used Unicolor roller bases at a tag sale. Started to process my film still in the JOBO tanks but atop the Unicolor rolling bases... was a lot easier that rolling in the JOBO, setting it up, and taking it down. Was very pleased to find out that my processing consistency did not suffer at all. So now haven't been using the JOBO processor for more than a year.
Year or two ago, always figured that I would sell the CPA-2 this year and purchase a CPP3. Modifying the darkroom to permanently house the CPP3 not a problem.
Now i'm wondering...Is the JOBO CPP3 processing unit an overkill?
I have a friend who uses a permanently stationed CPP3 in an auxiliary sink. He loves his set up.
I also have used the JOBO processor to process silver gelatin prints instead of using trays. Takes a bit longer to do, but in then in the end, making multiple identical final prints so easy to do.
