Announcement Plugin

I want to add a simple announcement plugin to my site at http://www.catholictravelblog.com. I am pretty new to WP so I want to do it right. It will be used for announcing certain events held at various locations around the world, with a start date and end date. I will either add it to my categories section or just put it on my home page, not sure which would be best at this time. I know there are a couple of these plugins available but wonder if anyone has suggestions as to what the best one would be.

Thanks
