All of these sites are known for being some of the top paying survey sites on the net. On average you earn $2-$3 per survey but I have been paid up to $10 for one survey. Also these are real surveys, not offers for signing up for other sites.

http://www.surveyspot.com - been paid $80 by them in a couple months (with more pending)

OpinionOutpost.com - 10 or more surveys monthly, been paid by them

SurveySavvy.com - started with them recently, haven't been paid, but if you google them, they are known for being one of the best paying sites.
