Bean-to-cup machines have a reputation for being awful unfortunately... Plus they're usually "top end" models so they'll probably be more expensive than buying an entry level machine and grinder. All the ones I've seen were £400+, and you can do a lot better than that. Whittards once stocked one that was £990 and could be fully automated to start brewing different coffees at different times of the day, so you could set it up to have a coffee ready for you first thing in the morning. It even had wi-fi so the engineers who made it could do remote troubleshooting on it for you

But what good is all that if the coffee is mediocre?
