with regard to photo flo, someone gave us about a gallon. Years worth, the real kick is that I feel that Edwal's is better. inital cost is more but it really is worth in *IMHO* and easier to measure. A drop is really a drop with the dispencer .
I stopped using Kodak products years ago when they stopped supporting B&W photography except as some one else suggested HC110. That decision was not made lightly but in line with their managment decision as to the loss of product, it made sense. It is sad that this move made by many people myself included, has lead to a loss of many tools we loved. It is hard to spend money with a company that does not care about it's customers.
