This has probably been discussed ad nauseam here but I wanted to add my .02 dollars anyway. I recently purchased a Jobo CPE processor to do black and white film. It is a dream. After initial testing I have been running large batches of film using T-Max developer with replenishment and it is great. I was a bit concerned when I got it that the agitation would be too intense and cause surge. It doesn't. I can put on a movie, get the developer to temp and just process 'til the cows come home. I can do 7 rolls of 35mm or 8 rolls of 120 at a time. (This is not a misprint, the reels can hold two rolls of 120 at once.) I HIGHLY recommend this to anyone who does black-and-white film at home or for a small studio. I have never been much into doing color. Until now I did black-and-white by hand. I will never go back. Once you get past the quirks of the Jobo you will love it. I had actually slowed down in shooting for fun. Now I can go out and shoot to my hearts content and know I am not going to be spending a week in the darkroom. I did 17 rolls a few days ago without even breaking a sweat.
