My experience with JandC is very limited, but very good. I've bought 100 rolls of the Surplus MacoPhot UP100+ they had for sale a while back, and judging from it, I'll buy hundreds more of their film. Remeber, kodak and Ilford screw up too (isn't there a recall on XP-2?). I think that if they are willing to fix it, give them the chance.
And no, I don't work there either, but they might be our saviors when the big corporations modernize and go the digital route.
