Migration – Drupal to WordPress

[ Moderator note: moved to Fixing WordPress. ]

I have seen a few Drupal to WordPress plugins, and have read mixed reviews on them. Has anyone had any recent success with moving a Drupal site to WordPress? I am thinking that improvements may have been made in products, and/or new methods may have been discovered. I also wonder if such a movie would be partially automated, and partially manual. I am looking to move a Drupal 6.1 site to WordPress. Does anyone have an advice or tips? Thanks.
