In SoCal (in my price range but rising fast), I like the SGV, specifically, Diamond Bar, Walnut, Puente Hills and E/SE West Covina. I also think Baldwin Park is cute in a quaint sort of way (like Chula Vista or Concord) but more urban than the other cities I mentioned. I like this area because it is very well-planned and not overbuilt, and, more importantly, will never be overbuilt. I also like the generous, even very generous lot sizes and the large supply of one-story homes. The only drawback is the heat for 9 months per year, which can get oppressive.
