I am considering purchasing some equipment to do my own sheet film processing. I have been using a JOBO Expert Drum to process my film at school. I like the "daylight" processing aspect of the drum, and I have had good results. The downside is that they are really expensive. I am interested in the BTZS tubes, because of their price. And also, though I do not use the zone system or grade paper, I think it would be nice to have the ability to do individual development times if I decide to go that route later. I guess the real question is what have your experiences with either or both of these products been? What would your reccomendation be? I don't have much space to use for the BTZS and trays, but I think I could do it. What do you all think? Thanks in advance, H. G.
