RSS freeware

So I want to play around with rss feeds, and was wondering if anyone can recommend a rss feed freeware program to use? :)

RSSOwl from http://www.rssowl.org

I just use ff's live bookmarks, but am about to try Sage, a ff addon.

well im playing with feed demon right now and will try others if it doesnt please me. :)

thanks for the suggestions. :)
