Living up to its name, Freeway Express is free. Sparkle could become a real gem, but it needs more polish first. Its preset page sizes for responsive design also work better in concept than reality. I think Sandvox would make a great choice for teachers and students, or for parents who want to help their kids build a fun, basic site.
And changing the whole look of your site is as easy as choosing a new template. Sandvox loses points for its limited customization and big but outdated selection of designs. But their considerable cost could quickly add up to more than you paid for RapidWeaver itself. If you want to branch out beyond its small slate of templates, keep your wallet handy. If you just want to pour your content into a limited set of sharp-looking templates, with responsive design already built in, RapidWeaver will work great.
