[2F/2F]

The listing on Photographers Formulary's site is hard to find - it is under "Developers - Holography" and is mis-described as a developer kit, rather than a complete kit.

It is also nearly $30 for one liter, plus shipping, which is ridiculous for the number or rolls you get out of it. One shot use gives you four rolls, so over $8 per roll. Go through the chems twice and you take it down to over $4. You have to go through the chemicals four times just to get the cost down to a bit over $2 per roll. And then you have bleach that is still good for 8x as many rolls as the developer used one shot, but they don't sell separate developer. This means that you have to buy the whole kit again, which includes bleach – by far the most expensive chemical used in the process – that you don't need until you go through another 7 batches of developer one shot. At that price, you might as well just use a lab and enjoy the extra time and darkroom space you get by doing so.

A few years ago, before Kodak discontinued their 1 gallon C-41 materials, I used to spend $70 for enough chemistry to equal two one gallon kits, or about 7.5 L. I bought two developers, two fixes, two Final Rinses and one bleach. I would get 60 rolls at the very least out of the two gallons, going through the chemistry only twice, ad then get even more by cross processing or developing less critical negs on the third time through the developer. (You can go through it up to four times, or replenish.) On top of that, I could do it with a six mile round trip and support a local business. So, my cost was around $1 per roll going through the chemistry only twice, plus random extras. Compare that to the $4 per roll cost of using the PF/Rollei kits twice through; they are nearly four times as expensive per roll as the 1 gallon kit, which was already more expensive than the bulk chemicals at the time. Buying the bulk chemicals probably takes it down to 50 cents a roll, though that is only from memory; I'd have to do all the numbers again to know for sure. Is it really going a good idea to pay PF or Rollei 8x as much just for decanting and labeling chemicals that can be bought directly by the home user?

I really think it is in our best interests to buy the bulk chemicals. I was excited to hear about the Rollei and Photographer's Formulary kits, but they are priced far beyond reason.
