Good looking contributed themes for Drupal 6 I am looking for good looking contributed themes fro Drupal 6. Drupal.org is filled with themes, although several of them lack support even for the most used modules (taxonomy, search, comment) and many are table based or written through bad and horrible practices.

What I would like to see are modern themes with great typography, grids, good coding practices, based on starter themes, making good use of CSS3 features, supporting other modules. I know it's hard to see a theme with all of those qualities, but try to match at least two of these.
While not definitive, looking at the list sorted by number of installs is probably a good place to start regarding coding standards, and wide support.

Further filtering this list using some of your keywords like 'starter', 'css3', 'html5', etc should help you find what you are looking for.
