The freerolls are fun and good for a player to practice, hone his skills and add a bit to his
bankroll now and again. And for those who can't afford to deposit $50-$100.
Just something to think about based off my 20+ years experience....
If you can afford to deposit $50-$100 you can start at 2nl full-ring(double table at least) and make $300-$500 in a few months(depending on variance and your volume). Playing freerolls could and likely will take longer and maybe much longer to make $500. Once you get to $500 freerolls really aren't worth the time as now you're bankrolled for 10nl. With $750 and shots at 25nl are just around the corner if beating 10nl comes pretty easy.
Cheers!!!
