I can only agree with you.The crazy thing about these threads is that I can never figure out, other than availability, why people wouldn't just get over it and use a stop bath.
Less time, less hassle, less complexity.
And about availability: Citric Acid (15g/ltr.) or Acetic Acid (99,5% (Glacial), 15% (cleaning) or white vinegar) should not be any problem to get one of these.
In the practical way when I am changing the fixer (6-10 films 500ml) I am changing the stop (Citric Acid) too. I do not like to keep working solutions over a longer time. And if you look at the costs of some chemicals, it's a fraction of the overall costs in photography. And for the work: I like liquid chemicals, fast and easy, no hassle outside the darkroom with powders. Making a new set (stop + fix) is just minute work.
