Gray's Paint store in Burlingame is a great place to go when you're looking for Benjamin Moore paints. I've been there several times now and always find the folks that work there to be extremely knowledgeable and helpful.
They have an outstanding selection of paints including a new designer series called C2 that's pretty cool. A little more expensive but a great color palette to choose from. The C2 paint will require two coats but didn't require a primer. I painted over a blue wall with a new tan color and managed to get by just fine with only two coats.
Only complaint would be the hours they are open on the weekend (Saturday until 4, Sunday closed).
