Best one I have found that pays via check is Survey Lion. It is for Canadians only but it pays up to $10 a survey and personally have got a $9 and $10 one and many 2-4 dollar ones.
On average its $10-15 a month which is a nice little extra. You get an email for each new opportunity so you dont have to wait and keep checking back for new opportunites.
I have completed 95 surveys over the years but was very inactive for a long period, i could of earned much more if more active.
I have another survey platform i earn on and will share next post.
I have $18 i will get around December 15 or so lol . NIce little Holiday present from the Internet. :)
