Steph: I can't comment on the Jobo, but as I indicated over on RFF, my experience with E-6 (Tetenal 3-solution) in regular stainless steel gear/water bath was great. I just centred myself, made sure I was focused on al the variables (temp, times, etc.) and got the job done. Beautiful chromes emerged, and the only reason to go with lab work was convenience. But you don't have local convenience, so do your own, I know you will be successful.
If you are going to get the Jobo later, just shoot a test roll and process it manually with the gear you have for proof of concept.
