Dungeness Crab and Alaska King Crab
If you type crab into the search box on the top of the page, you'll find suggestions for Dungeness. There is also a thread from Aug 25th, if you look down. As for King Crab, I usually only see it frozen. You could call the best fish stores--University Seafood, Fresh Fish Co, Mutual Fish or Uwajimaya--and see who has it, if it's fresh or frozen, etc. All of those are quality places.
