The Kodak chems are great if you can get them, e.g. the 4x5L kits. There was a thread a while back that said room temp worked for Kodak papers but not Fuji; I can't confirm because I run it at 35C as recommended.
As an alternative to Fuji, Freestyle sells their Arista brand. I'm not sure if it's an older revision of FCA or whether it's from a different manufacturer, but I found it to work with basically the same filter settings as FCA. It doesn't have the Fuji printing on the back and the base isn't quite as white as the latest FCA, though you can only see the difference side-by-side and it's very very subtle. I also suspect it has a little less magenta/green crossover than FCA but can't be sure just yet.
