Besides Ipsos, Zoompanel is another survey company I love. Sign-up is free and you should get several surveys a week from Zoompanel.
Their surveys are well-designed and easy to follow and you are fairly compensated in Zoompoints for your time. You can redeem your Zoompoints for various prizes. I have received several products to test in my house through this company and can highly recommend it.
If you forgot to sign up for the Ipsos survey panel I blogged about earlier this week, check it out and sign up soon!
