I jumped right in and developed my own.
I have a simple method, take a big container and put my chemical bottles in it, along with a gallon jug of water. Then pour in hot water 20-30 degrees hotter than the working temperature of the chemicals and wait 30 minutes. I can add hot water to keep the chemicals stable at 104 f. I do all this in the bath tub as the container is pretty large.
Its really very easy to process your own E-6 or C-41. I thought it would be much harder than it actually is.
I can tell you, the first time you take a 4x5 color slide out of the daylight tank, its magic.
