welcome to the world of coffee.
Loads of choices, so you need to narrow it down.
Pod machines:
Down side: not a true taste of the real deal coffee and relatively expensive pods.
Upside: v v convenient.
Bean to cup machines:
Down side: relatively expensive to buy
Upside: Good ones make OK espresso, they have built in grinders for beans and will heat the milk/froth
Hand fill espresso machines (with water pump)
Down side: bit of a faff and you need a grinder also.
Upside: great coffee, bit of an art to make the stuff if that/s your bag.
Stick down your specifics and the collective can advise.
