You can find some dofollow search engines on this post - http://directoryblogger.com/are-you-tired-of-looking-for-dofollow-blogs/
there is nothing urgent about linkbuilding, it is a long process, in the time you take to find out whether or not a site is no-follow or not I will have posted 10 more comments, so I would say that you are wasting your time.
