Where can I buy meiwa kumquat in Socal?

Does anybody know a nursery or private party that sells one or are they still banned?

I've seen them at various nurseries around San Diego.  However, they usually aren't available until mid-Spring.

Clausen Nursery actually propagates them on-site:  http://clausennursery.com/citrus-trees/kumquat-trees

I've also seen examples at Anderson's and Armstrong nurseries.
