I used to write at Merchant Circle and that was reliable. I got paid each week but the small articles didn't pay that well really. It was still dependable though. I think Blogsvertise is by far the best I have used. You write posts on your own blog (which is good) then you provide links back to other sites for webmasters. You will make around $5 to $25 per post.
You just have to be sure where you are linking back to is relevant and will not hurt your site in the search engines, as far as quality goes.
