I haven't had much experience with paid survey sites, except for those which conduct surveys based on online matters. The reason for this is that I am not from the U.S, and most surveys are for those in the U.S.
Unfortunately I can't give any account of my personal experience for the first two, except I have seen them higly recommended quite often.
Although I don't use paid surveys much, I decided to post the results of my previous research here.

Gozing Surveys


Spider Metrix:
This is the only one I consistently use and can be a good way to make money online.

• This is the only paid survey site where I have actually taken a survey, qute a few at that.
• It's based on online matters, and you earn points, when you reach a certain a mount of points, you can redeem for different things, including cash.
