Catalogue recommendations?

Hi.

This is my first post in the forum, I hope it's in the right place.

I'm busy with a site and need a good Product Catalogue module.

It is pretty basic. There will be about 15 different categories, each with a number of products in them. Some of them may need to have sub-categories.

Each product needs to have a brief description, product code, and possible space for it to say "out of stock".

It should have thumbnails which can also be viewed as a larger image.

I would like to be able to search the catalogue in a few different ways. Eg - by keyword, code, category etc...

It needs to be simple for the end user to add or remove products, etc

Any recommendations would be greatly appreciated!

Thanks!
