Blanconegro fills this niche to some extent, but it's restricted to foma products. If you could be an Australian version of ag-photographic in the UK, I'd be quite happy
I'd be interested in being able to find kentmere papers more readily, my local doesn't stock much of a range, but they have plenty of Ilford. If you can get a roll of 36/ex HP5+ down below $8, I'll buy it from you.
