Living in the valley was actually much cheaper for me than Miami. That's from housing to my car (the lease was cheaper out there, so I waited till I was situated to get one) to food (jack in the box value menu ftw). I'd suggest living with others, as the 1 bedrooms do seem to be higher priced to rent. Gas is never fun, but that's most of California. Take the 22 or 522 bus. It runs 24/7 down el camino and costs 60 bucks a month for an unlimited pass.
