looking for reputable machine shop in SF/Bay area

Hi folks, I'm in the north bay, and I'm looking for a reputable machine shop in the north bay if possible. Does anyone have any recommendations? If absolutely needed, I suppose I could go to the south bay or sac, but I'd rather not have to buy the little lady any more bribes of jewelry to make the gas expenditure, "Oh I guess it's ok to drive that far sweetie, and thanks for the new necklace" Don't laugh, Happy wife = happy life! :banghead:
