$25 for a pretty superb WYSIWYG editor with CSS and JavaScript support, in-app responsive design tool, selectable themes, etc. I enjoy it. I'm not at all into coding front-end design, which is always a project-stopper for me. Something like this makes the GUI part easy, even though it's "just bootstrap".
Bootstrap is so simple you don't need WYSIWYG.
