During the recent google farm update, ezinearticle and articlebase were one of the top sites, who lost their rankings, because they staged spinned contents. Both these sites are still not penalizing those users who submit spinned content. But, they make some actions in the future. Spinned articles may just lower your reputation.
If you still want to go for one they you can search for article spinner by submit suite.

I think article spinning can be one of your option as long as you edit/polish the article after spinning. What I do is , I mix around 3-4 articles on the same topic, spin them and re-write... And VOILA! I always get positive results.
