According to me it depends of the amount of your bankroll, if you have 50$ IN THE BANKROLL, I think you can make tournaments 'stng) for 10$ buy in not more (1/5 of your bankroll).
It would be stupid for instance to bet all your bankroll for 1 tournament and even if you can win x 2.
Well I also think you can earn money on Freezout GP which offer interesant amounts!
Finally as Scrawnny told you you can use the banner of the forum to download the room and take advantage of freeroll which offre nice amount for free huhuhu
