There you can set something like this as a filter and only shops that offer the device version you are looking for will be displayed without you having to look at the manufacturer.

I often end up at Galaxus in this way, but the article description in the shop is still very much in need of improvement, so I use Geizhals as a portal for searching for Galaxus articles.
