RSS Poster – Free Version Review
Usability
Very easy to set up the RSS Poster. This is also due to the fact that there are not many options as you can see below.
Pricing
The plugin is free. There is a professional version as well. The professional version I have not tested. It seems, however, that most of the features are reserved for the paid version.
Features
You can only add up to 5 RSS feeds that you want to autoblog. You can assign keywords to them. You can schedule when and how many post RSS Poster is to get.
Best thing is that it grabs full posts. This feature does not work for all feeds, though (I had problems with a feedburner feed)
And, well, that is basically it.
Customization
You can schedule when RSS poster ought to get the posts and in which category it shall place them.
Support
Not tested

Great free plugin but allows to add only 5 blogs. Anyways, will surely use it!
