What is the best blog network to get backlinks?

I tried Authority Link Network, but most of their sites have fake page rank, or are de-indexed by Google. What are some good blog networks to get backlinks from?

I found the following backlinks to my target that could only have come from Authority Link Network, and I checked the page rank, and nearly every one of the domains has a fake page rank!

Only shotgunmythos and healthpartners had a real page rank, and they were N/A or no rank at all. point908 isn't even indexed by Google!
