I just bought Mamiya RB, and consider to buy Jobo CPE2 or like processor. What I want to say, don't be afraid. After all, if you build that darkroom, you can allways buy few hundreds (thousands?) rolls of film(s), few hundreds sheets of papers, freeze that, and you can allways buy chemicals or give to some chemistry technicians to mix developer and fixer from raw chemicals for you. So, you can have years and years of analog photography to enjoy, no matter of future photography business (and I don't think film and rest will disapear in next decade or two...)
