I am thinking of getting a Jobo CPP-2 rotary proccessor (with lift) to develop my 135 and 120 films but I also thought it would be nice to also develop my prints like that with the 2800 tank series. My darkroom is small so if I am able to process up to 50x60cm (20x24") prints that would be really great as even 30x40cm (12x16") trays take alll the space. I would like to know what you think. 1. Should I get the 1500 or the 2500 series tanks? I am not planning to move to large format any time soon as apart from the camera and lens that would also mean I would need a new enlarger. 1500 series are more economic but with 2500 you can fit more film. 2. What tanks should I get for prints? I am at the moment printing 13x17cm (5x7"), 20x25cm (8x10") and 30x40cm (12x16") both in RC and FB but thinking of doing a somewhat rare print up to 50x60cm (20x24") if the photograph and the occussion demands it. Should I get two or three different ones for matters of economy of chemicals or just the large one would suffice? 3. What water connections does it need? From what I understand it also has a cold water connection? 4. If you feel the tempeting basin with water once, I assume you don't really need to change it often as the water is not used, right? 5. Any other piece of advice?
