I'm using MagpieRss for a while now and I think it works great.
I do have a problem though.
Most feeds are parsed, but with some I get:
Fatal error: Only variables can be passed by reference in ......./rss_parse.inc on line 351.
For example, the feeds of IGN give this error (http://scripts.ign.com/rss/ign.PlayStation3.2.0.xml). Other feeds work great, so I'm really confused about what's causing this problem.
