It depends on what you’d like to spend upfront and then buying coffee. Nespresso, the new pod ones (if you don’t mind the pods) is quick, easy and clean. We were spending £60 a month on coffee. Now we also have a De’Longhi machine, bean to cup. Spent a bit more up front, but the beans can be far cheaper. We spend £60 every 3 months or so now, cheaper decaf in bulk and the treat ourselves with good quality caffeinated.
I like this one if you are into espresso type coffees: De'Longhi Dedica Style, Traditional Pump Espresso Machine, Coffee and Cappuccino Maker, EC685M, Silver https://amzn.eu/d/iqRTl7Z
