PineCone Research is my favorite survey company, and (according to some of my friends) the best one out there!
First of all, unlike some other survey companies that has a minimum cash out amount, they send you checks the first business day after you complete a survey. They pay you $3 for surveys about 15-20 minutes long.
During the surveys, they will show you a picture of an ad for a new product, and then you'd have to answer some questions about how you liked the ad, and if you want to buy the product...etc, so it's pretty easy to do. And at the end of the survey you will be asked if you want to receive a sample of this product for free, so this is kind of like product testing too!
There is 1 downside to this company, though. Not everyone gets accepted and normally you'd have to find a banner that links to their website to sign up...
But the banners are still pretty hard to find,
Good Luck!
*Update: I have gotten at least 10 payments from them now (wasn't really keeping track), and even a new product for me to test! The checks came about 3 days after I did the survey online (faster if you use PayPal), click here for a proof of payment.*
