I think there are pretty cheap flights from LAX->SFO. You could also look into Amtrak (which I think only goes to Oakland, which is ~2 hours away from Stanford by BART and Caltrain), but often Amtrak's just about as expensive as flying. If you're really looking for cheap, there's buses like Greyhound, but they're slow and you'll encounter some sketchy people. But I think they've gotten better, and some buses even have WiFi.
