i played in a $100 freeroll at ftp the other night for 5 and a half hours and got 10th place, just missed the final table...and got a sparkling rich $2...couple more of those and i'm goin to mcdonalds
a lot of the smaller sites have lots of freerolls, pitbull has a $25 fr every hour with top 18 getting paid, the players there are horrible, and most of the regulars have some attitude issues. if you play late at night there will only be a couple hundred ppl, at peak hours there's only 500...of course i think you have to make the final table to get more than the sweet 30 cents you get for it. poker4ever has $25 fr's at 2/8 am/pm every day, they pay out a lot more places so you could donk it after an hour and walk away with 3 cents! they're incredibly easy to cash, i think i'm up to $5 in my account there playing in them and i haven't played all that many...those tourney's have no ante's at all at any point which makes it so much more easy. carbon has a handful every day around 9:15, 1:15am or so are the one's i've noticed...1500 ppl, i think you have to final table to get any money, i haven't played many and got a dollar once, they also have those play money steps sng's for a dollar.
ultimate bet/absolute have a bunch a day where you don't have to play for the first hour, for the most part, and of the 6000 ppl who entered there will be 1000 left by then and you'll still have most your stack, top 18 get paid out of the $50, top 30 get a ticket to a $1000 fr. bodog has 2 $500 fr's a day right now, ~3000ppl, you have to get around top 63...it probably has the worst play still going on at the late stages, which is pretty frustrating at times...when you're AA still gets cracked by 26o.
doyle has nightly 10pm fr's where the top 100 get tickets to a $1000 fr on sunday where i think top 50 get paid, you usually get around 1000-1500 ppl in those fr's and its not hard
