I'm interested in knowing what tools people use daily and why. Many of us use keyword tools, domain tools, backlink checkers, page rank tools, meta tag generators, and others. So which do you use daily? What are your favorites?

DP keyword tool, g keyword tool, Y keyword tool, Keycompete, Seo chat Pagerank checker backlinks etc... Plus my own tools i have had created

-there are many seo tools paid and free
- I start to collect free seo tools that every one can use them in just one squidoo lens:

and
I every time use all tools offer by Google webmasters

For a web designer who designs his own site, I use to use seo tools about 3 years ago and have not used any since apart form "overture keyword tool" a few times just to see what were the best keywords to optimize my main pages for.

I don't really use much tools anymore.

I prefer using digital point seo tools and SEO Elite program.

I use SEO Elite and it seems to do what it is suppose to but the results can be misleading sometimes.

I use the SEO tools of http://www.smartpagerank.com/. It works well!

I've purchased SEO Elite and Keyword Elite and they've helped.

I'm monstly a Regnow affiliate so i've also purchased the well known Ultimate Regnow Affiliate for some of my sites.
