When I moved to Europe years ago from the USA I was trying to decide if I wanted an all-in-one or an old-style arm one like you link (they were bigger though with lots of brass and just one arm). I ultimately went with the all-in-one (with ceramic grinders) because I realized I was so tired of grinding my coffee, packing it in, waiting for the espresso maker to warm up, having to stand there while the pump runs (I know this step is different), take the filter off and empty the grounds... if I needed to make 5 coffees for guests it was a big long ordeal. But my Italian all-in-one is super convenient but expensive but worth it. It's been twenty years now and I had to services just once. Select what I want to make, go off to my computer to login while it grinds the coffee, makes the coffee, go pick it up. Simple.
