Ask HN: Which health plan should I sign my start-up with?

We recently got some funding, enough that I want to start paying salaries and benefits (for all 3 of us). What health care and benefits companies do people like? (We're all in California.) I called Trinet, they are advertising all over the Bay Area, but they basically told me to call back when I had 20 employees. That point is far enough away that I would like something else now. Any suggestions?
