You can buy the E-6 chemistry from Kodak that you can mix for 500ml at a time to be used one time. Once mixed the chemistry is good for about two or three weeks if you don't have all the air removed. You will also need to keep the chemistry at 100ºF ±.5ºF on some of the critical steps so you will need a temperature control device to do that. Those run around $300.00. Getting one of those Jobo processors is a good start, but otherwise you are in for a lot of hassle unless your good at fabricating a set up yourself. Once you get started developing both time and temperature are critical so there is no room for screw ups.
