I'm in Calgary, and I have used the Argentix kits and they seem to work fine but you do need to keep the temperatures under control (as with any colour process). Velvia 50 turns out a bit dark so I'd lengthen the first developer around 20 to 25% if that's what you are using. I ended up getting a Jobo CPE and I bought two of the the Fuji-Hunt 5-litre 6 bath E6 kits from Freestyle. I used WorldWide Customs to deal with the logistics of importing ORM-D and it was no problem - but it did add some cost. Maybe my cost for the chemistry is $7 or $8 per roll, unmounted, not including the 35 or 40 minutes of time, plus I use two litres of distilled water per roll for rinses. I bought the kit so I could do it quick-turnaround instead of waiting for a couple of weeks. If I was in a city that had overnight E6 processing available I would probably not do my own E6, the cost difference isn't huge. I do use proper PPE when mixing and running the process and I recommend that. VOC-rated mask, face shield, apron, big gloves, basically everything as recommended in the MSDS. The 6-bath chemicals seem to last about two months after being mixed, provided I use some of the chemical preservative - the stuff from Tetnal that contains mostly propane should work, I just use propane from a torch. Propane is heavier than air so it forms a layer right over the chemical and prevents oxidation. Good luck!!!
