Ezinearticles is the best but it is also very strict. You need to follow their TOS to get your articles accepted. Some other directories worth exploring are Articledashboard Articlecity Ideamarketers Searchwarp Goarticles Articlebase Gather is a relatively new site that has high PR and instant approval.

My tip. Set a precise amount of time for article marketing each week (e.g. 3 hours). Start with Ezine & then generate individualised content going downwards in PR/Alexa score
