Thanks guys.

Greg, I read that sticky and the rest of the thread. I also downloaded the two spreadsheets for separating out chemistry from bulk purchases. The point I'm confused about is the starter replenisher, which is why I'm opting for the SM route - I think that means I avoid that. I guess I wanted to get more than just the one liter kit as that seems kind of small for tweaking the process (I assume I'm going to go through a few rolls of film just getting everything right and consistent).
