That makes sense, completely, but I purchased it because it makes life so wonderful and easy for developing E6 and C41 in one easy shot. It came with the Jobo Water mixing panel as well so I get my temps right on to the 1/10th of F. Degree. It's already paid for it's self, even with purchased chem, over and over again. And I used Target for .99 a roll for my daily stuff.
