Finding Articles to Re-Write?

Now then BHW, I need some help thankyoupleash.

I'm looking for articles to re-write, articles which are already targeted to certain key phrases.

It's a mega pain in the arse searching for these through Google, or using several article directories so i'm looking for either a search engine which only indexes article directories, or better yet, a piece of software which can extract articles from multiple directories.

I've already tried 'content magnet article extractor' and it wasn't very good.

Any suggestions?

Thanks
