Since many of us have good knowledge about Classified Scripts(php) I have some questions for them to find a good classified system(stand alone is ok too). Suggest Open source or commercial close to the following features.

Features should be closed to :
1.multiple images per item
2.multiple category and sub category
3.customizable fields(add fields, searchable etc.)
4.user rating and reviews

Actually I am planning to create a product review site with various products with multiple images(lite version of CNET.com).

I tried Noah Classifieds. which has features 2 and 3.

So what do you guys recommend?
