Oh I forgot to add that at least mypoints uses some of the listed above and others for surveys. vindale.com ( I have tried and was ok. I got paid but lots of work for not always getting into/doing survey although there are higher amounts you have to buy and so 35 might be like 10.00 after you buy things so be careful) and panda research is similar.
