I've used them for years, in every darkroom I've ever taught in. The 1+9 dilution ratio makes mixing effortless, and you're right about the vanilla-scented stop bath. I use the print dev, stop, fix, and wash aids myself, but am staunch about Edwal Sodium Sulfite + FG7 film dev for fine grain. However, my students' film always looks great w/Sprint dev (when they do it right, anyhow!) When I went online last Fall for their standard film dev chart to print out for the school darkroom, they were apologetic, quick to respond, and quick to fix the problem when I e-mailed them about part of the chart being cut off (of course it was the part that I needed!) Definitely support the local company, and, IMHO, *ANY* company that supports US as film users.
