It looks like everyone either buys a kit or looks for bulk Flexicolor chemistry. Cool. I'll probably do one or the other—because I'm a noob and it's good to start where others have started (so others can help you out).
However: when I started this thread, however, I really did want to know if it's even possible to get as simple a setup as we can get developing B&W. David Lyga seems to have the most interesting minimal setup: Flexicolor + Sodium Carbonate for a cost effective developer solution, Potassium Ferricyanide for bleach, and any ol' Fixer. I'd like to know about others—no matter how unwise it is. (It's good to know this stuff, right?)
