OsCommerce Module Addition

Hi, I need to add a component to my existing OsCommerce site. I need the ability to order products in any order I choose from the admin. I would like to be able to put certain products next to each other, certain products at the top... I just need more control as to how they are displayed in the front end. This is the existing site: [login to view URL] I have found a few contributions on the OsCommerce site, but I'm not sure what the best option is. Products exist in multiple categories, sometimes 5-6.... I'm not sure how it would work with this. Here is one that might work, but I am not sure: [login to view URL] It would be nice to be able to put a number in the product attribute, like 1, 5, 10, 15, 20, 25 and so on, so that I can add a product in between others if I need to, without having to re-order the entire set. Thanks in advance!
