Here at The Day Job we're using Scout(http://scoutapp.com) to monitor about 10 servers - it's pretty easy to set up, and grows well as your cluster does. You also get to write plugins in Ruby, which is pretty fun.

Yeah, looks like exactly what I want. But the cheapest option is more expensive than all my infrastructure put together :(.
