Good question. You have to do your homework on GPT sites. Some can be scams but most are legit. A good place to start is by checking out GPTBoycott.com
After taking a look at the names of the sites that are known frauds, it's time to pick a reputable site or too. I am an experienced user of GPT sites and can tell you some of the more reputable sites to start off with. The first one I would recommend is Paid The Fastest. (Here is the link: http://paidthefastest.com/members/register.php?ref=jameshood ) This site has been around for a long time and lets you cash out your money starting at only a dollar! That is an important thing to look for, in my opinion, when choosing a good GPT site. I use them daily and attest to their honesty.
Another great site I use daily is called CashPirate. (Here is the link: http://cashpirate.com/members/register.php?ref=jameshood) Again, they have been around for quite a while and have a low minimum payout of only $3.00. That is very easy to achieve, probably within your first hour on the site.
The last site I am going to recommend is called PrizeLive. (Here is the link: http://www.prizelive.com/r/jameshood) This is a wonderful site that rewards you in many different way, including contests and daily rewards just for being active. You only have to make a single dollar to cash out.
I hope this information helps. For a more complete list of GPT sites that include snapshot pics, reviews and much more, you can check out a great site called Free Links For Cash. (Here is the link: http://freelinksforcash.webs.com/apps/links/).
Good luck with your new money making adventure!
The best is always Mturk
The best from my personal experiences is Amazon's own Mturk.

I am active on there and have made well over $1,000 in the past 6 months without anything more than an hour or less a day when I am bored. A lot of it is just when I am watching tv and doing other things at the same time, so its pretty nice.
