So far I've started one of the online focus group panels. I was kind anxious what it would entail but, it's really easy and fun. The two I am participating last 3 days.
I would suggest these two online focus group companies to get you started:
USA Talk Now is a nation-wide network of people who make a difference. Members participate in online surveys and focus groups, sharing their opinions and preferences on a wide variety of topics while earning points that can be redeemed for a variety of great rewards.
Gongos Research is looking for people to join their online market research community, which they have called the Consumer Village. As a member of Consumer Village, you will be given the opportunity to participate in a variety of different studies and programmes, and they claim that as a member of this community, you will have far more ways to participate in research than you would with a traditional survey panel. Their secret, according to their website, lies in the fact that they will make a large number of surveys available to members, each of which earn points for completion. These points that are awarded to participants can be transferred for amazon.com gift certificates
