Help finding a plugin

I run a fairly large site and I am considering migrating to a full wordpress solution, however I am looking for a plugin that can manage my software directory. I have over 30 freeware software titles that I need to manage, allow users comments and rate all the while having a landing page. (http://www.zeropaid.com/utorrent) That is what I need to replace with my wordpress plugin.

I have checked out wp-downloadManager, wp-downloadMonitor and DrainHole but they really don’t meet my needs, and besides there is no landing page or way to comment on the downloads.

Can anyone recommend a free or $$$ plugin that can do all this for me?

Thanks
