If I were you I would lean towards Southern. They have a stellar rep on this forum and they are close. But, I would get a custom build of what I wanted and not just one of their ad packages. If it really doesn't matter get one of the packages, you can't beat that service deal. Come to think of it, I was going to say check the prices of other builders with stellar reps, but that service deal makes Southern the hands down winner.
