Pingdom, SiteUptime, and Montastic. None of these are relied upon for mission critical monitoring. I set them up as a sort of "canary in the coal mine" for each of my servers, to help alert me to issues. I also created a very hacky, browser start page which has GIF's that are pulled from each of my servers. Sort of like how "game copy world" used to setup their mirror page. Super unsophisticated but it allows me to do an "uptime check" every time I open my browser.
