Yes, I'm a member of several private sites but only 2 that I would classify as good- Demonoid and Torrent-Damage. The others have a good selection but very few peers so it's almost impossible to maintain a good ratio. Have to be very selective. Of the public sites, I liked Isohunt and Torrentspy but recently got burned on a file at Isohunt with nearly 200 seeds and over 3000 peers. I knew to stay away from files that had never completed but not those with seeds so it's private for me from now on or IRC.
