Here is a program that is free to help with rewriting articles. DupeFree Pro - Avoid Duplicate Content and Online Content Plagiarism. I think you will really like this program. It is also very easy to use. Thought that I would just add it in here for everyone to see.
Hope this helps everyone,

Thanks for that link...

I downloaded the software but haven't tried it yet.

The product page has a goldmine of information about dupe content and seo.

I particularly liked the video interview with Vanessa Fox from Google's sitemap team. She answered a lot of questions I had about how google uses the sitemaps and where their real value lies.

Great stuff!

I tried to compare original PLR article with rewritten and what do you know - two softwares bring me different results.

DupeFree Pro v1.1.2 detects 43% of unique content.
Content Checkup v1.30 detects 76% of unique content.

It seems to me like one of these softwares is out of date.
Maybe i am wrong, but what software should i trust?

Here you want to see another different result try
DupeCop - Online and desktop tools to detect duplicate content

Okay let's sum up the results of 4 duplicate content analyzing programs i used so far:

1) DupeFree Pro v1.1.2 detects 43% of unique content.
2) Content Checkup v1.30 detects 76% of unique content.
3) DupeCop online version detects 51.7% of unique content.
4) WordFlood version 2.0 detects 68% of unique content.

The results are different probably because some of programs work differently when analyzing Google's duplicate content formula which is not known to anyone outside of Google.

I should ask this program developers.
