I came here for a smog check a couple weeks ago. The man who rang me up and gave me my paperwork was really nice and personable. They also have a $20 off coupon you print from their website, which makes the whole thing about $40, $50ish with tax. If you have the Stanford student coupon book, there's a $30 off coupon (which I found AFTER my smog check, doh.). The guy broke down the different numbers that are on the smog check report, which was helpful. And told me that my brakes were in good shape. caveat: I'm not actually sure what's a normal price for smog checks in the South Bay, I mostly came here because it was close to my apartment.
