im looking for one that pays well and you dont have to pay to join. and you get paid pretty frequently
I work for an online mystery shopping company...they are absolutely free and they pay weekly...there is no costs to you ever! http://www.secretbuyer.net/members/reseller_manager/sponsor3/emilybw.html
I've actually looked for one that works before, and haven't been able to find one that doesn't require you to complete "offers" beforehand.
