Why do you need a hub? have you checked the servicing guides for hubs in the downloads. Might be the brake rings rather than the hub that's broken. I ended up changing to manual locking hubs because of the brake rings.
If you really are stuck I have a pair of free wheel hubs after I converted to manual.
No idea about price but I'm sure we could come to an arrangement :augie
Or you could go down the manual route with these :-
