Developer & Fixer - Developer gallon-Pink

Most 4 gallon (yes, 4 gallon) developers/fixer pre-mixed sets for processors with rollers span from $43 - $55.00, including mixed developer/fixer options. Shipping varies. Kodak,is the highest with 4 gals. of fixer topping in at $82.00, ABX the best buy at the above prices. Reasonable self-mixing sets cost c. $24.00/quart and yield 1 gallon of product (i.e., GBX). These prices are as of July, 2013 from a dental supplier (i.e,Dental City, Darby D.S.). OTC suppliers for non-health care personnel should therefore run less because of the significant mark-up among dental/medcial suppliers, but may not sell to the general public, so draw your own conclusions regarding the review item cost ($$). Furthermore, be sure to determine if your processing fluid is suitable for processing machines with or without rollers. Also try large photo supply providers (B&H, Adorama, etc.)for dark room chemicals available to the general public. I have not experimented with cross compatibility of the chemistry, but plan to do so. Last of all, beware that if you buy in bulk or mix from concentrates; you must be extremely accurate with storage and mixing ratios, because developer in particular deteriorates rapidly above 70 degrees (refrigerate developer per se; fixer stores well at room temp).
