Making Money with Online Surveys

After a period of about 2 years of using the internet for profit, I've come up with a list of my best and worst survey companies. Now these opinions are based solely on my own experiences with the companies, nothing else. Here is what I have to offer you. Take it as you will.

Best Companies~

Opinion Outpost- This is by far my favorite company. All you do is take surveys that they send to your email address and reap the rewards! I got a check in the last 6 weeks for around $30 and have made another $12 already. It won't pay the rent, but for a little mad money, it's not bad at all.
Global Opinion Panels- I've made about $10 from these guys and while the surveys aren't as plentiful as some, it is pretty easy to do.
Erewards- Good prize packs. Have $24 credit at this time.
Mysurvey- I've made $10 from this company, but I don't know about the prizes/rewards.
Mypoints- EXCELLENT company to work with. Click on emails and visit websites to get points that you redeem for between $5-50 worth of gift certificates. Vendors range from Walmart & Target to Olive Garden, Applebee's, or Omaha steaks. Not the quickest way to earn lots of money, but nice to do when you check your email. Probably the easiest company that I have worked with.
Hipoints/Harris Poll Online- This is another slow way to earn rewards, but the surveys are super-easy and more interesting than some. The prizes are varied and include some pretty fun stuff.

Worst Companies~ These are companies that take far too long for me to earn any substantial points. I've given each one about a year to see results and now that the results are in, these are just too slow!

Mindfield
Ipsos I-say
Opinion Central
NPD Online Research
Ithink
Cafe Zoom- Have rarely heard from them since I've belonged.
American Consumer Opinion
Mills Advisory Panel
PSB Surveys
Epoll- These are pretty fun, easy surveys but the points take a while to accumulate.
Global Test Market


If you know of other good or bad companies feel free to email me. I will update the list if I get enough feedback from it.
Have a great day!
