We use the Gene Images(TM) random prime labeling module (Amersham
Pharmacia) for non radioactive labeling. The anti-Fluorecein AB that came
with the Kit seems to work good when new, but to weaken quickly.
And as far as I know Amersham Pharmacia does not sell this shelf life
limiting component separately.
A similar system for ISH is in use in the lab next door and they had mixed
experiences with it. I cant say if their probes of labeling was crap of if
the kit has problems. 

I hope this bit of experience helped you
