Same here.
The Nop Electronics seems like a little bit outdated now (The style, color, font and layout). Even comparing with your template site: nop-templates.com.
Also I always doubt the necessity to create so many different types of themes with different names on it. It may be a better way to focus on two or three themes and then make it versatile, flexible and easy to customize to meet different requirements. Just like what Magento theme Ultimo does now like below:
http://themeforest.net/item/ultimo-fluid-responsive-magento-theme/discussion/3231798
The theme can be customized to be used in total different industry, from fashion to electronics.
Hope this request can get some feedback from 7spikes. :)
Thanks.
