I worked with event handlers on my last project and I wanted a quick and easy way to add/delete my event handlers. I found a pretty cool application on CodePlex that let you manage your own events. After enabling the feature, I was able to view all my events, add new ones, edit or delete them, and all this from the UI. Before using this application, I was using SharePoint Manager 2007 and went to each list to see what events would be associated to it.. that application centralizes all the events which I thought was very useful, check it out here!
