I'm not sure the fact it's hurting one company means it will hurt others. The lower price for Efke [well not here] might mean they had less room. Or the other companies may have longer term contracts. Personally I think it might be a good thing. The more users for the product [in this case the celluoid] may lead other companies to produce more of the celluoid. In the long run that may mean film will last longer.
Me I use cheap Agfa and leave these expensive films alone-)
