Some of the shops here are small with limited opening hours, you might want to call them before going there. But small doesn’t mean bad, they mostly have a very passionate owner and you can properly learn a lot. If you want to see the results on a map, go to Map Search and chose Shops in the left side. I you look for something special you might want to go to the Manufacturer page and search in tags e.g. “Background” or “turntable”.
