I have a delonghi autentica, got it seriously on sale in the Amazon day, like several hundred off. Probably wasn't the latest model, but nothing that mattered - what mattered most to me was the small footprint, and having one that did both coffee and milk automatically. I didn't pay anywhere near this much: https://www.amazon.co.uk/gp/product/B00MOIE1E2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
Things I like are the detachable milk jug to go in the fridge in between so you don't waste milk; the fact that all the bits of the milk carafe can go in the dishwasher; the separate space for ground coffee if you want to add decaf or whatever for just one person, and the small footprint. Mine fits on the worktop, underneath the kitchen cupboards, with enough room still to get the water carafe out and filled, and to fill the beans hopper. I've only just got enough room to do that though; when you look at the specs of the machine, the height sounds like it will fit fine, but it's easy to underestimate how much extra height you need for the water and beans, if you don't want to be pulling it out all the time. Of course if you have plenty of space on other surfaces and don't need to keep it underneath the cupboards, even better.
What I don't like - it doesn't tell you when the beans are out before it starts making a cappuccino, so it does the milk first, then starts grinding and then tells you there aren't enough beans. Obviously a more organised person than me would have always checked that the beans hopper was full..
It's also very very needy, but that is true of all bean to cup machines. It always wants something, water, beans, cleaning the milk, descaling, changing the filter, emptying the grounds ,whatever - it's always beeping at me like a toddler seeking attention.
I've had a couple of problems, once with the O-ring seal wearing out, but it was under warranty; another time I think it was a similar problem, but a lot of descaling seemed to fix it. They were quite good about collecting and returning it and efficient with repairs, which is handy - this was DeLonghi in the UK who dealt with it.
I am still trying to find a coffee bean that I really really like, though.
