Hi
I like IOpenUSA, i have been member of this surveys panel for the last 3 years and i really like it a lot, they have improved with time, a lot of surveys to take every day (most days more than 400), the minimum amount to cash out is low, only 12,50 USD for PayPal(in fact i cash out q/2 days or some times daily) and amazon is only 10 USD,
My best Regards
James
