Pinecone Research is still accepting applicants in some demographic groups. I personally use this company and have been very happy.
Pinecone Research sends between 1 and 4 surveys a month and you are paid $3.00 per survey. Payment is paid through Pay Pal and is usually paid within 3 business days of completing the survey. I have also received higher paying surveys and some people receive free samples to try for market research purposes.
