If you are just starting - a good developer is Agfa MC developer - A PQ developer- it is super cheap, does a great job and lasts forever. All good things for practicing. Then when you get that magic negative and want to make a gallery image - try a glycin based developer (formulary D65 or other) and make your fine print. No sense in spending a lot of chemisty in the learning phase. Les Mclain wrote a pretty good book that covers several kinds of printing techniques that I am using with good results (lots of ideas there - thanks Les) - anyway - If your experience is like mine - there are more so-so prints than great prints at first and might as well do them on acceptable lesser cost materials.
