Thanks David, but I can't figure out the Kodak naming schemes, and don't know what to buy. According to the PDI site, I'd have to spend quite a bit to get much larger quantities than I need. I had it figured out a long time ago, and then products started disappearing. I think I need a simplified kit unless there are stable, low-volume individual components available. Any specific hands-on info on the SM F1 and F2 kits would be very useful. I'm also putting out feelers to a few dealers regarding the Trebla kit. Seems really quite cheap for what you get.

I do not need RA-4 chems.
