Just saw this product listed on the megaperls site. It wasn't there last week.
8x10 is available in grade 2 or 3, costs about $100 aussie for a box of 100 sheets.
Also available in 4x5 and half-plate, apparently grade 3 only.

Is the legendary Fuji Azo type paper that has been referred to in various other threads? I'd love to hear a review from anyone who has used it. Unfortunately there is no in depth product information available at megaperls - e.g. paper chemistry.
