I've played with RapidWeaver as well as SandVox now, and they both seem to be fine products of their type. I slightly prefer the feel of SandVox, but RW has far more in the way of third party themes/templates. You can customise both their themes quite easily. If you want a quick solution without having to know about what goes on underneath, this is the way to go.

I tried iWeb as well but didn't like it as much as the other two.
