Well, I didn't catch a lot of yeahs for Rodinal. I stand by my reason for its recommendation. But, really the idea is to get started developing film at home. Doesn't matter what developer, as long as the OP experiences success (and joy).
All the talk about practicing with the reels has me wondering...are we talking about the stainless steel jobs? I use those and love them, but not what I'd recommend for a beginner. The plastic reels that you load with alternating twists is the one I'd suggest. Very, very difficult to mess it up with those. I have a few of those reels and tanks in my defunct darkroom (I'm film develop and digital print nowadays). I think the brand is Patterson. Hmm, Houston is a ways off from Oregon. I'd gladly hand the OP one of these sets to help spread the enjoyment of film but I don't know if it would be cheaper for the OP to buy locally or spring for the shipping.
I gotta try that Caffenol process. I've seen some wonderful results. I don't know if those nice examples are typical output though.
