Hi Fusebulb and all interested -- The way the site is organized it really is optimal for users if each item (in this case model) is listed separately by format rather than bundled into one that contains multiple format versions.  If it is bundled users won't be able to find the item by the format type that they need.  Not bundling is also better for contributors and the site since it will generate additional page views.  Please don't bundle as this defeats the purpose of the pull down menu search by format functionality.
