http://torrentscan.com/This site is very simple and it includes over 10 different well-known torrent search engines.
It includes
SeedPeer, SUMO Torrent, BTjunkie, Bush Torrent, Fenopy, isoHunt, Mininova, myBittorrent, The Pirate Bay, Torrent Box, and Torrent Reactor.
It used to also cover
Demonoid [which was the best quality site I have ever seen.] but the government sucks balls and downed their server.
You'll see on the left is a checklist of the sites I mentioned. Type what you're searching for in the search box and click on the site you want to search. The main body of the site will then search that site and return your results. If you don't find what you're looking for at one site, check another one on the left and it will automatically search what you've typed in.
This site makes searching for torrents much more manageable and instead of you finding the correct site, it comes to you, in this one site as a whole!
Good luck, happy torrent searching!
