James, I was wondering about the flourite, here in Tokyo (Land of the 
Unstable ¥) I can't find a similar product. I really don't want to use 
Amano's goods (I'm not independantly wealthy) as he doesn't pay me enough to 
deserve product loyalty. (¥8,000 a page for written copy). I'd also like a 
source for some of the Jobes stiks, fertilizers here are all of the liquid 
type or fast disolving types.
