I have a league just like that....
This is the best league you'll find with the most dedicated owners.
New Auction/Keeper League with $30 entry fee (all dues go into the pot) currently with 10 owners and looking for more...hopefully 12-16.
League Site: http://www.home.earthlink.net/~auctionfantasy/
This is a well-organized league with, as the league page says, "Football Fanatics." All of the owners are highly active and competitive. If you join we would like it to be for the long haul. Finding new owners for orphaned teams is a pain in the ass.
