I love using Divi from Elegant Themes, it's so clean and easy to use, even for clients who aren't very tech-savvy.
Karen of Karen's Kurriculum Korner had a problem with a bad webhost, so we moved to the far more reliable GoDaddy and took her site to the next level with a much-needed facelift.
Just for kicks, here is what her website looked like before I updated the theme and added her new logo.
