I'll second Pinecone. I've been a member for 2 weeks and already got paid $10.
I just started SurveyDirect and qualified for my first $2 from paypal. Not a lot of money, but since it took me about 2 minutes to do the survey it's not too shabby. Once I get a new computer in the next few weeks and get moving a little faster I'll spend more time looking through the surveys they have available.
I've also had success with InboxDollars - just got a check a few weeks ago for $60. It's not really surveys, but you get paid to sign up for trials, mailing lists, etc. You get $5 to sign up. You also get $5 for each referral. You can cash out at $30. I signed up for all everything that was free (using a junk email since you know you're getting spammed from those places) Then when there were any programs that I wanted to sign up for, I'd check there and see how much payback they had. I switched ISPs and got $10 both times.
I've also gotten $20 from CreationsRewards in less than a month and I'm a few more 'signups' away from another payout.
I've also gotten $75 in gift cards at MyPoints over the past 9 months, and just a handfull of points away from another $25.
