Do you any legitimate survey site to make money online?

Legitimate survey sites are hard to find because most of them requires investment. Either you need to purchase a package of survey forms or the training package. I am a member of 2 legitimate sites. They pay, but I cannot assure you of the fast earning on said sites because surveys do come very nominal. What I mean, it takes so much time when another survey comes. If interested, just let me know.

Lightspeed consumer panel is a good one. It takes a while to earn enough points to get a reward, but I have earned two amazon.com gift cards and one paypal gift card there. There is also a search engine called swagbucks that is legitimate, you can earn points to get rewards or gift cards. I am also looking for more legitimate sites to earn money with if you know of any.
