I've been using the MLB.com fantasy leagues for about 5 years. The statistics engine is powered by Sporting News and runs real-time scoring while games are in progress. I also like CBS Sportsline's league as well - they have a really great analysis staff. It's all preference really...most all of them have different varieties to whatever you desire and the price range you wish. Pearl of wisdom for ya - cheaper the price - less competitiveness, lots of people give up in the middle of the season if they didn't spend much $.
