Just wanted to point out a content rewriting service I was introduced to lately. Maybe some of you already know about it. I haven't used it yet but it is definitely on my list. I will use it to rewrite plr and to rewrite articles I purchase to use not only on my own sites but in web 2.0 sites and wherever I need it like uaw.The rewriting is done by humans on a sentence by sentence basis. You can get the output in common spinner syntax too.
It is http://www.humanrewriter.com/index.php
There is also a wso for it from a couple months ago: http://www.warriorforum.com/warrior-special-offers-forum/93938-humanrewriter-com-get-up-15-trying-our-top-notch-rewriting-service.html
