It's not really PR8. The PR8 url gives power to its subdomains and so its not a full PR8, just a very slim portion. I wouldn't spend too much time on this.

Ya that is right Sbfc which you have shared here. eHow,Blogger and Stat Counter are free and PR8 backlinks. Really very good collection. Thanks for sharing.
