As I'm not an agent I'll give you my biased opinion. :)
I agree with Jeff and Mary that the Woodlands is quite nice; a self-sustained community. It is, however, almost an hour north of Houston.
I live by the Galleria mall (about two blocks from it), which is an easy drive (or walk, even) to so many activities, restaurants, etc. If you are a single woman in her thirties it's not a bad place to be. Were I to move, I wold move to the west or central side inside loop 610.
If you tell me what your parameters are I can give you more advice. :)
