We're starting up a league that fits some of your perameters.
It's auction (online!) and just $40.
However, it's mixed - but w/ 16 teams, the competition is heightened.
Also, our draft isn't this weekend but the morning of Opening Night (Sun 4/3).
Here's my post about it... http://www.fantasybaseballcafe.com/foru ... p?t=100492
Worth a look maybe?
