Is RB worth it for a small stakes player?

[Asufiji2004]

Sorry total noob when it comes to this, but I was wondering if it's worth it for me. I play maybe 15-20 hrs a week. Mostly .50/1 or 1-2 limit, some NL and small buy-in tournies. This is a hobby, but free $$ is free $$. Should I stick to bonus whoring or is setting up rakeback at a site, a good option for me? Any ideas as to the best site for a player like me?

Thanx..sorry for the noob questions.
