Rated 5 out of 5 stars
Currently the best torrent metasearch engine out there. Others may have more sites, but Torrent Meta Search packs the most features into the smallest, least obtrusive package. Doesn't bombard you with ads, or do who-knows-what like a plug-in or extension.
Besides sortable categories, my favorite feature is that it also shows comments and screenshots on mouseover when available. While it doesn't completely replace every torrent search, it covers the major sites and is generally all you need. THE go-to torrent search engine. You won't be disappointed.
