[wp-hackers] rss aggregator plugin for WordPress: hackers' recommendations

[Denis de Bernardy]

I've found quite a number of available rss aggregators for WordPress. In no
particular order:

I'd need one that creates posts out of feeds. I understand several of the
above can do this. 
I'm curious to know if any of you have experienced difficulties using them.
