The USFL is a deep (45 man roster w/ IDP) 16 team dynasty type league at myfantasyleague.com. I have around seven guys right now and I'm looking for at least eight more.
The cost is $10 per team. First place wins an NFL replica jersey of their choice.
Here is the link, feel free to look around and checkout the rules.
