What is the best SEO Tools?

What I've been using :

1. Scrapebox - very powerful scraper
2. spinnerchief - very good free spinner
3. magic submitter - the best and the most flexible backlink tool I've used.

I have autobacklink bomb and bookmarkingWiz but kinda dusty ... MS can do their tasks more easily!

Go the Blackhat way to get your SEO tools and save those $500. Consulting fee for this post is $50. See?! I just saved you $450.

Oops, sorry... this is the Whitehat section of the forum.

Market Samurai
Google AdWords Keyword Tool
SEOQuake + SEOforFirefox (Firefox add-ons)
All-In-One SEO (WordPress plugin)

These come to "my" mind right now.

thanks for your whitehat suggestions!
