http://www.rtsports.com is good so is the new draft and drade though the Sportingnews. Both those site alow you to setup your league without paying first. After you get the info you need, just don't use that site again, and don't pay. When the season starts and you haven't payed, they will close the league you set up.
Also http://www.myfantasyleague.com works for that too.
