Since years I use zFeeder all over my growing site of some 4000+ content-pages to promote my own feeds / new content as well as to include remote News-feeds.
Once configured, zFeeder works perfectly for years to come - absolutely maintenance free. I love the WAP feed, the easy to use or modify/adapt templates with CSS. Easy setup, easy configuration and zero maintenance. zFeeder output/display can be configured in so many ways to satisfy all possible needs including mRSS with pictures.
