Yes, we are using some of their products at the college where I work. In the process of switching over though, our local shop ran out of the film developer in the middle of last semester and didn't know when they would get more stock in. Now using Xtol for film and contemplating other options for paper developer and film/paper fix.
I have been using their Rapid Fixer for years. I used to purchase it a Keeble & Shuchat in Palo Alto but since they closed, I've not found a new supplier (but, I admit that I haven't looked too hard).
So, am interested too!
I believe that Lauder Chemicals is still in business.
