Pinecone Research is my favorite survey compnay! Their surveys are very straightforward, you never screen out after investing time into a survey, and they pay $3 per survey (and pay you after each survey, via check or Paypal). They only open for new sign-ups once in a while and it never stays open long....so hurry! Click here to sign up!
You can also read about the other survey companies that I use and recommend in this post!
