rishabhsood.net has a list of 1200+ blogs. Courtney Tuttle's list is very popular. You can also find similar list at other bloggers. I would recommend that you head over to http://directoryblogger.com/dofollow-blog-search/ or http://www.inlineseo.com/dofollowdiver/ to find lots of dofollow blogs.

Why don't you just use a dofollow search engine like the one I have linked bellow called the "dofollow blog finder"?
I'd suggest confirming that any of these free resources are accurate. In my experience dofollow search engines and lists are only about 50% dofollow.
