I've never used a 3rd party one, so I can't recommend one in particular. I'm sure there are a few about if you Google, just see which works best.
If you want to tweak one or build your own, gimme a shout.
If you did want to build your own, the direction you should be looking at is parsing XML:

Headlines generate a RSS feed which is in XML (specially formatted text). You load this and parse the information you want out of it.
