First of all I was broswing for info on processing ECN film at home [in C-41] and want to say thanks for that. On the issue of cost. For B&W if you buy raw chemicals in reasonable quanties then costs drop quite a bit. I buy sodium sulfite 10lbs at a time and I know those who buy full bags [50 or 100lbs] The stuff keeps and is used in almost everything. Off the top of my head 1litre of D-76 stock would be around 80cents. Maybe $1. That's buying 10lbs of sodium sulfite at a time. The cost of D-76 may be mostly sodium sulfite but it's also a relatively cheap chemical. For comparison I buy 10lbs of sodium sulfite for the same price I buy 1 lb of metol. For E6 the trick is to avoid kits. Buy the jugs aimed at minilabs. The bigger jugs are much cheaper. Considering the volume you guys do I don't see a downside with buying the bigger jugs. If you have the equipment at home you can run your own control strips. Densitomters are often sold cheap on Ebay. Even without you may get a local lab to check your strips.
