We have recently released JM-Electronic-Equipment template in two completely various versions - taking into account website functionality.
The first one - JM-Electronic-Equipment uses DJ-Catalog2 joomla component to create a products catalog of various manufacturers, segregated in categories. You can also display product price but this component does not allow to buy online.
The store version - JM-Electronic-Equipment-Store uses VirtueMart component to allow buying online.
Take a look at product description that is divided into tabs - we have installed here our free tab plugin for VirtueMart - DJ-VMPageBreak that works in the similar way as a standard Joomla Page Break plugin.
