Easy to configure but with enough options to make it highly customizable. Works without issue. Highly recommended for embedding simple Javascript into one's site.

Easy to install, configure and manage. Simpler to use than docman, but with the same usability and supports 1.5 natively.

I don't think people can fault the administrator's support commitments, this guy has provided a free and open source solution that anyone can add to, maintain and support themselves.
