Thank you Steve for the kind offering.
I managed to solve the problem now, I placed a call to process-supplies and talked to the man there.
What I was looking for, was to buy a huge (for me anyway) quantity of Fuji Neopan 1600, they are about £1 cheaper on the fujilab site than at other places, and I was also un-sure if they would have such an amount in stock.
Process-supplies had loads in stock and the rep. said that they could even get hold of more, as Fuji seemingly had started to produce it again. He wasn't sure if they would keep producing it though, but for now, it was possible to get hold of. (He was, understandably, a bit frustrated by Fuji's lack of predictability)
So, run out and buy some if you miss it! ^^
Pentaxuser, indeed, I checked now with the two mentioned stores and ag-photographic had the Neopan 1600 listed.
I've found it in 7dayshop, ag-photographic, process-supplies and at fujilab. (only p-s and ag-photo ships outside UK as far as I know)
