Looking for script for software skins directory site

Hi,

I'm going to create a software skins/themes directory site, I've tried to look for a script to be able to manage the contents easier, but there are so many scripts out there, and I didn't find any that really suit my need. Basically I need a script to manage the website contents, and have such some features like the visitors can give any comments/reviews on some skins/themes.
Does anybody here know if there is a good script that can provide the features as I said above? For this time I'm trying to find the free ones but if you know the paid ones, just tell me, I'll take a look at it as well.

Thanks.
