I would like to have seen a demo site where I could check it out without having to setup a project. Looks good from the screenshots though.

Another rails admin alternative is https://github.com/fesplugas/typus

I have been hooked on Typus for 1.5 years now. It goes on every project.

Looks promising. Does anyone know any other alternatives?

I've been using the admin_data plugin on both 2.3 and 3.0 projects.

I'm using ActiveScaffold which is useful both for admin and the frontend (but no Rails 3 support).

Volker's fork works great on Rails 3, and also supports jQuery
