SC or DP would be my first affordable choice. I wanted to buy in there back in the early 90's, but small major fixer-uppers was all we could get at the time. Got a brand new home in a new (at the time) area of inland O'side for the same or less price (similar distance from ocean as La Costa or Rancho Santa Fe).
Good luck and say hi to Rickoray reef for me, if you get up there. The place was fickle, but has it's moments.
I'm sure it's changed a lot since the old mobile home park has been fully re-developed into high-dig custom homes, ala Ritz Cove style.
