I've been looking for a place that I can buy extremely high PR/ domain authority links that are in strong sites with good content. I'm aware that it will cost me, just curious where it would be available?

sape.ru. I think tommy runs a BST for sape links.

Http://Text-link-ads.com is great if you want really high quality.

You can pm me if you are serious about these kind of links, I can refer you to a service Ive used for a few years that works really well.

Google is a good idea?

You can build your own private network on tumblr with pr3+ and PA35+ for few bucks per domain!
If you are interested then add me on skype: Rasacz
Thanks

I got a random email from a company that offered an about.com article with a backlink for $300. Im not sure if thats a good deal or not
