Best RSS Feed Aggregator?

Hey everyone. I am looking for a good aggregator to put maybe ariund 30-35 feeds into to display on my blog. The site I am creating is mostly just going to be made up of the posts from those feeds, but I can’t find a good simple aggregator. I am a beginner with wordpress, so lamen’s terms would be appreciated. I liked FeedWordPress, but there’s a glitch I couldn’t get past. Please Help
