Based on this thread I decided to try out both content gorilla and textbroker. I ordered 4 articles from both and compared them against each other.
Content Gorilla was half the cost, but it definitely showed. CG delivered in just under a week, whereas textbroker delivered in a few HOURS. As far as quality goes, there was no comparison. The textbroker stuff was as good as I would have written myself. The CG stuff was clearly not written by a native english speaker. Of the four articles I got from CG, I would feel confident putting only one of them on my site without major revisions.
