Whats the best article submitter?

I bought The best article spinner and spend a lot of time rewriting a good quality article. (each sentence has 3 variations, most phrases have variations and obviously a ton of word synonyms etc.) Now, I've been submitting them to some popular directories, about 20 in total. What would be the best tool to summit already written articles to directories for me? I want to choose which ones I want to submit to and what article. Something free would be amazing, but I'm willing to pay some money for a good program, whats is the best tool to use for this?

the best way is to use Imacros custom script or better check this video http://media.thirtydaychallengeplus.com/30DCPLUS201001SD_TU05_Link_Building_Part1.mp4 - I am thinking of bying acess to one of these article networks.
