WordPress-powered Web catalog?

Hello all,
I am looking to set up an online Web catalog for a local business, with item listings much like the ones found at http://www.frontiertruckparts.com/showinv.aspx?xtype=cam. I do not need a shopping cart; however, I do need to categorize the items, and also have a details page for each individual item. Does anyone know of a plug-in that would work well for this project? Any help would be appreciated. Thanks!
