Looking for Leonberger breeder

[StompinTania]

Hi, I am searching for a Leonberger breeder. I am looking for a very calm and stable Leo, and feel a bit overwhelmed in the breeder search. I do not live near any breeders, and in fact, a visit to a potential breeder would involve a flight across the country. I am willing to do this, but I want to do as much research ahead of time as possible.

Any thoughts? Good experiences? Bad experiences? I have seen references to hyper Leos, and it seems to me this should be a fault - from all the reading I have done it would seem they should never be considered hyper. I want to avoid this if at all possible.

Thanks!
