AmpSurveys looks at lot like the kind of survey panel I would recommend avoiding. You do surveys and maybe you win a prize...
Open to US, Canada, United Kingdom, Australia.
They say that if you join their panel you will get opinion surveys and contests, no mention of cash. The company (Ampario) is owned by OTX Research who I know, and am reasonably positive about, from doing Movie reviews. Maybe it just looks bad?
Anyway, if you decide to try it, use an email address that you don't need to rely on, and let me know what you think. AmpSurveys.
