What equipment do I need to make espresso at home? Excuse the rookie question, but I am a newbie to coffee. (I blame my nationality; I grew up with tea. ;) )

What equipment, exactly, do I need to get from coffee beans to a cup of espresso that I can drink?
Easiest thing is a bean to cup machine like any of these, these will grind a pre-measured amount of beans, heat water and pump through into your cup and dispense the used grounds into a grounds bin internally.

Going the other way you need a minimum of some form of grinder (preferably burr type) which can be manual or electric.

A 'normal' espresso machine like these which may or may not have a milk frother.

You can opt for a digital scale machine to weigh your beans, possibly mineral water if you hate descaling your machine.

The scales are for measuring an accurate amount of beans, I do this because I have a manual grinder. The water is cheap still mineral water because I live in the south of England and the water is so incredibly hard that it has tattoos.

Also you need cups to drink the final product.
