Suggest a theme work with products


I need a theme for small company, they don't want selling their products on-line, they just want to show all the products they got, no shopping cart.

I remember ever seen some themes can showing products (actually they are "posts" with feature image defined) on homepage with slide or grid view, and click the image can bring you to the post.

What you guys do ? Using e-commerce solutions like wp-commerce or marketpress to define products and show them ?
