Spinning an article is quite probably the best thing to do, because I am sure you have heard the opinions about duplicate content. However, I always make sure I submit the best draft of an article to Ezine, as I believe that is the biggest and best article directory.
I just recently heard that as long as you change the title around, and make just a couple little changes; that duplicate content is not as big a deal as alot pf people believe it to be.
On the flip side of that coin, I really do believe that unique, quality content is always the best way to go. So, If you can get your hands on an article spinning software, I think you should.
But, I submit to ezine first, let it get approved, then I will submit the same article to the other less formidable directories after it has been approved by ezine.
I know that was a little long winded, and I apologize for that. I hope I helped you in some small way
