Ya, most the vintage stuff I've found doesn't come from local sources. Weird Stuff in the South Bay may have a few things in their bone bins, but after looking a couple times I concluded it's better to buy something off eBay than spend time looking through boxes and boxes hoping to find something vintage.
Seems like a decent place to go hunting, though I think it will be more contemporary parts. I may go to the Santa Rosa one this Saturday, and there is one in Sunnyvale.
