Survey Spot is one of the best survey sites around. They offer a lot of surveys where you don't get paid anything (you get entries into a sweepstakes) but the paid surveys you are offered more than make up for it. I just did a survey where I got $50!

The only drawback to the site is that it can take a while for paid surveys to be posted to your account. But this not a huge deal, and they are very fair and honest. If you like surveys, I highly recommend joining this site.
