Backlink Monitoring & Alert Tool Recommendations

[Choice]

I'd like to receive alerts for new backlinks to my site and monitor all current backlinks to ensure they do not get removed or changed. Can you recommend some good options for this?

Decided upon http://monitorbacklinks.com and am happy thus far. Great support and accurate backlink data. Their advanced report feature uses the ahrefs api.

the free tool i use is google alerts, you can type in as many urls as you want and google sends you emails when your url has been linked. Its free and without all the hassle.
