Over the last several years, I've tried out pretty much all of them. For smaller environments, the cost of most of the commercial (hosted) monitoring systems is just too damn high. I've currently got a pretty extensive Opsview deployment keeping an eye on everything for me but I'm about to begin setting up Zabbix to replace it. None of them will do everything you want, so I'm going with one that will meet 90% of my needs OOTB and will allow me to take care of the other 10% myself.
