Why spend money on Auto Blogger Pro/RSS2Blog when you can have the same thing for free?
My CMS of choice is Drupal (
http://www.drupal.org) and they offer what you need. Here's an example of an automated blog running drupal in action ->
http://drupal.org/planet
All ya really need to use is the news aggregator (
http://drupal.org/node/21963). But whatever goodies you need you can get (ie Google SiteMap -
http://drupal.org/project/gsitemap). Just check out
http://www.drupal.org and look around at the many modules they offer.
Drupal is SOLID, they have huge support (ie irc - #drupal @ freenode.net), and you dont have to be stuck to just a blog. The options are endless with drupal and it's FREE, unlike the others
