My chemistry is the C41 Developer Replenisher 19 liters which runs about $25 plus the starter which will do many many gallons but costs $8 plus your bleach which I usually hunt ebay and found a third party selling Bleach III for $25 for 5 gallons. I use flexicolor fix which is also cheap plus the stabilizer which freestyle is selling on ebay. If you want to buy directly from kodak you can get the Flexicolor SM bleach in 3.2 liter containers. You'll have to hunt for it though.

Either way you need developer, bleach, fix, stabilizer/final rinse. I use developer one shot, fix and bleach two shot, and mix up stabilizer with distilled water, one shot as well. You can push them many many times that capacity but I prefer to get guaranteed good results than save money.
