There is a sticky in this category where I listed what to get and where to get it. But if you are going to get SM chemicals, get this developer kit. I would look for the catalog number on that page and google it since B&H won't ship it. It is the only Kodak kit that does not need a fourth part called "starter". Be aware that the kit I linked to is only the developer, it does not contain the bleach, fixer, or final rinse. If you are going to just try this and see how it goes, get the 1 liter kit from Photographer's Formulary, it contains everything you need and is Kodak brand. If you want to get larger quantities after that, you can get the individual parts and be off to the races.
