If stat-tracker is indeed $10 this season, then if you have a league of at least ten owners, try talking everyone into getting a premium league. That's what my long-running keeper league did this season.
With ten teams, the $125 works out (obviously) to $12.50 a team. For the extra $2.50 (or $4.50 if stat-tracker costs $8) the entire league gets stat-tracker, as well as the draft kit and premium updates.
For those of you in free leagues, do you guys get the "assistant manager" feature, or no? I guess it will provide you with a suggested starting line-up.
I also know that if you want divisions, head-to-head scoring that just results in one win or loss for the week instead of a per category score, Yahoo to review trades (I think), and the ability to run Yahoo's live online draft on a Saturday or Sunday you need to be in a premium league.
