For awhile I've been relying on the official pages of Wordpress and Joomla along with a few design sites like SmashingMagazine, NetTuts, and Mashable for finding outstanding templates and useful plugins for clients.
Still, I've noticed recently that the sources I've been searching haven't been able to help as much with plugins as templates (since those are easier to plop on a list and post) so I wanted to know if there are any other reputable sources for finding plugins which aren't just landing pages for overseas developers (which is why I've given up on Google in this case)
