It all comes down to your keyword selection, but I have had nothing but good results with ezarticlelink. I should mention that I do not use it exclusively though. It is just part of my overall backlinking plan.

EZA is a good article submission site, it would be more beneficial if you submit an article with unique and good content.

I am giving EZArticleLink a try now... looks interesting... I like that there is a free version to try out first..
