Once you go CBS, you'll never go back to Yahoo. We run a $115 league that will be a keeper in the first year. We have a core group of guys who return year after year. E-mail firstname.lastname@example.org
for more details; I know it's a bit more than you're looking for but if you noticed, the lower the dollar amount, the faster people bounce when things don't go their way and it brings the whole league down. We've found any leagues under $100 are typically not worth the time.
We're running 3 leagues this year, all through CBS Commissioner. $115 entry fee. $600/$400/$200 for places 1/2/3. One league drafts tonight and we need 1 owner (Mar 26), the first roto league is full. . .and the third league is Apr 2 and has 1 vacancy.
