where are you located ?
there is a great chemical system called sprint system of photography.
it is a system meaning the stop indicates ( from yellowish to purplish )
when everything is exhausted, not just the stop bath.
the chemicals are liquid concentrate stock and mix easy !:9.
if you can't find them locally they can be purchased right off their website
their developer ( film ) is sort of like d76 and id11 but a bit different
and i believe it is metol free.
good luck !
