It's neither open source, nor free, but I moved from Nagios/Groundwork to Solarwinds ipMonitor 9. Solarwinds recently cut the price down to under $1000 for unlimited monitors. Up until about a year ago, the unlimited license ran about $5K. So for a large nationwide environment like ours, our ROI was pretty decent, but if you are only watching a dozen or two systems with maybe ten monitors each, Nagios would be the best bet.

You probably have the list of the most commonly used. Each has good and bad points. A few of them I believe are limited on using agents and supporting external scripts. Several are considered Nagios on steroids, using a Nagios core wrappered in a bunch of other OSS. Several, like Zenoss are particular about the primarily monitoring system (though agents might run on any OS).
