Good points Ken! Though we can't forget that some folks are new to film, students, etc.; and that give-and-take-symbiotic-system can't exist (yet) because price is so much more important (vital)....
I wonder what the mix is of folks who'd rather get a bunch'a $2'ish rolls of low cost b/w film vs the $5+ roll-a-film-folks.....hummmm I smell a poll
For the record, I pay a lot more for APX100 here in the states because I love it! I am worried that any change to the emulsion will affect my art goals....so for me, I am like you describe the symbiotic buyer
