There are websites that pay per test for UX feedback, but I have found that it's basically the same situation with them too.
I think it helps to try several, see how long it takes to reach threshold between them all and try at it for a month or two. Even then, it would still probably be just supplemental income of a few extra dollars a year.
Out of anything, survey sites have been absolutely the most inefficient and untrustworthy. They sell pipe dreams and are ponzi schemes of sorts, funneling to other affiliate sites to sign up there for specific surveys allegedly. At least testing things out proves to pay something--seems rather generous in comparison.
Microworkers is the only site I know of that have surveys occasionally of $1 to $3 each usually. You have to breeze through them to avoid dragging each one out for 20 minutes or more, though.
