Not sure I'd call $20-$50 big time, but click the Sportsline ad on the left hand side of the screen and you'll see leagues with buy ins anywhere from $29.99-$499.99
EDIT: Depending on which of their ads are up, you'll also find leagues for $9.99 and free too.
Yes doctor, I am sick.
Sick of those who are spineless.
Sick of those who feel self-entitled.
Sick of those who are hypocrites.
Yes doctor, an army is forming.
Yes doctor, there will be a war.
Yes doctor, there will be blood.....
