I always thought the Berkeley was a very pretty bag but probably a little more pricey for most people to buy which is why it was not seen as much. LV has a tendency to phase in bags like this every few years and come out with new styles like the Siracusa and the Stresa. You should call the 800# to see if they can locate one for you.
I had a Berkeley Azur Damier. I got it at a local consignment store March of 2010. The person who consigned it had lost her job and wanted to return it, but LV wouldn't take it back. It had a couple of pen marks on the interior. Other than that it was like new. I paid around $899 for it. I loved it, but ended up selling it last year through Fashionphile. I got back what I paid for it, but I miss it.
