OK, this is ridiculous. Anybody who cannot find the basic chemicals necessary to make ordinary film and paper developers and fixer is simply not looking.
Right now, ebay seller "cjchemical", which I am pretty sure is a front name for Art Craft Chemicals
http://www.artcraftchemicals.com has the following listing:
Metol: $30 / pound.
Hydroquinone: $16.50 / pound
silver nitrate: $82.00 / 100 gram
Ferric Ammonium Citrate (green): $31.00 / pound
and many other useful chems
ebay seller "gulfcoastliquidators" has:
Sodium sulfite - $16.99 / 10 pounds
and many other useful chems
Borax is avaialble in the grocery store laundry detergent isle.
Ascorbic acid crystals are available at better nutrition stores.
Photographer's formulary also has all of this stuff and more at reasonable prices (and, in my experience, better quality).
Do not let yourself be crippled by fear. I don't know what good comes from well respected members of the community spreading fear and mis-information. Everything you need to mix your own D76, Dektol, etc is readily available. Just look!
