you can try to approach Frederf, Kinzonu or White Palace.... (in no particular order....)
alot of us got our maltese from either of them as they are reputable....
price of course will depend on the quality of the maltese and care given to them by the breeder....

its easy to say get another one.... but not easily done.... only a new individual will enter your life and form a new bond, but never ever able to replace the one that has gone, neither the bond that has fomed....
