I had a trial account a couple of years ago. They didn't seem to have anything I couldn't get elsewhere for free. A friend has a decent professional site with them. I am presently experimenting with Drupal Gardens, which is led by the inventor of Drupal. They are in beta, but were giving out invite codes a week or so, and may have some left. If you go to http://drupal.arisbe.net
there should be a link to them at the bottom of the page.
