I've been deliberating over which C-41 kit to try for very occasional (infrequent) development -- i.e. one or two rolls a month: The Arista liquid kit (1 Qt.) or the Unicolor powder kit (1 L). I'll be using a small Paterson tank. For most things, I'm happy to drop my film off at Target. Processing is 95 cents. But certain things they can't do (medium format, cross-processing), and other things I might not want them to do (critical rolls, Ektar). I've been developing a lot of black and white over the past year (D76) and I think I'm ready to try C-41. Thanks for your help.
