Not in California anymore

[Serengeti]

I have three questions if I may....
Normally I am not into wines very much, but while I was stationed (military) in California I was treated to a bottle of Talbott Chardonay (Cuvee Cynthia) which was like nothing I have ever had before. Very complex, yet very, very good. Now I am living in Florida and can not find Talbott anywhere.
(1) Does anyone know if I can order some online?
(2) Is there any Chardonay that is similar?
(2) The Talbott had sediment on the bottom of the bottle, but I was told that it is normal for the "Cuvee Cynthia" since it was unfiltered. Any comments on filtered vice unfiltered.
Thanks.....
