Backlinks to your site

I just came accross a web site especially useful for web masters. Its Backlink Watch.

We can type the URL into Backlink Watch and get complete detailed information about the quality and quantity of backward links pointing to the website. It shows anchor text, Google Toolbar PageRank, total outbound links on that page and nofollow flag for each of the inbound links available.

I compared the 'backlink watch' results for my site with the results from Google 'web master tools'; This site had provided a more complete and accurate information.
