Here's an easy way to search dozen's of the most popular torrent sites...all in one site.
What's even cooler about this site is that you can drill down certain genres, let's say movies, and you can see all the torrent sites that are dedicated specifically for that genre.
Of course, you can also search through these sites too if you don't want to browse. When you search for something, on the top of the results page, you'll see about a dozen different torrent sites. If you click on any of these, they'll show you what torrents they have in their collection that matched your search.
Overall, this is a pretty easy way to find ANYTHING online.
