If you can, make the trip down to Santa Cruz for Chaikhana. They sell puerh hand produced by master wang (here's an interview of him)http://www.teance.com/category_s/109.htm
. David (the owner) has loads of antique tea ware (his personal collection has stuff as old as the song dynasty). If you're looking for yixing, he just bought some from a collector (i just bought one from the 50's).
