I am probably even cheaper than you are
One litre of distilled water costs me 1 euro, which is quite expensive. I get the water at the local DIY store (Gamma) and know of no other source. I am willing to use this water for the dev, stop and fix steps, but not for all of the rinsing- simply too expensive. If the marks persist in such a semi-clean workflow then I will have to turn away from this film, which would be a huge pity, cause I like its look a lot.
