If you can afford to pay as you go, I suggest Plus-One Flyers out od Mongomery. Monthly fee of like 25 bucks, and Cessna's and Pipers at roughly $60-70 per hour. Lots of freelance instructors that fly out of there.
Also try out Gillespie. Just stay away from Golden State, or as the locals call lt, "golden mistake".
I got my Private at California Flight Academy. I really can't comment on them now because its been so long. Their management has changed over the years a few times so I don't know how it is over there now. I had fun though back in the day.
