Hi,
Google webamsters tools is best for me till now.
I just replied for "jason830" becauase he was showing some doubt with backlinkwatch tools.
So, I replied that backlinkswatch is good tools to check backlinks due to his feature. I did not use any tools to check my backlinks, i use some times backlinks watch or iwebtools to check my clients websites's backlinks to make a initial report.
Thanks
