If you're an avid survey taker (like me!), have you checked out MyView yet? I signed up a few weeks ago and so far I really like it! Haven't gotten any spammy emails, and I qualify for most surveys. They send you surveys based on your profile, so you're more likely to get paid the whole cash amount for the survey. Even if you don't qualify, you still get MVPs (MyView Points).
You can redeem your MVPs for Visa gift cards, and they plan on adding other rewards in the future. But I'll take cash! According to their FAQ, they also do product testing!
