Each color dev kit can yield 12-16 rolls of film dev for me. I use Bellini’s kit (I try to use their chemicals for all non BW film!) and the results are great.
Here someone compares the time and cost for each color kit. Bellini is almost as expensive as Kodak’s (I don’t want to deal with replenishes, comes in amounts that fit how I shoot color (12-16 rolls every 3 months).
I’ve got my workflow down and I really enjoy doing it at home.
