Though I would share a free backlinks tool. This will list you all backlinks to a site, plus show the pagerank of each backlink, and also list nofollow tags, or any other abnormal flags. Plus it shows the number of outbound links on the page that your link was found on. It also gives you the anchor text that is on your link.

The site is called Backlinkwatch.com.

It does take a while for the tool to run the analysis. I just ran one on a site that has 805 backlinks, and it took around 20 minutes to do
Enjoy,
