         | 
         | Pourover is typically brighter and less intense, but obviously

         | Firstly I would say that the grinder makes an outsize

         | coincidence also likes nice coffee).
         | 
         | Then I have a friend who is an ex-high-end-barista and gigantic
         | coffee snob (like coffee snob's coffee snob) and insists that
         | once you have a good grinder it's more important to get a
         | reverse osmosis filter than a high-end espresso machine. Make
         | of that what you will, but if you want to investigate that he
         | swears by this book[1] and having drunk coffee at Colonna and
         | Smalls in Bath (owned by one of the guys who wrote the book) I
         | can say he might be on to something. Certainly every cafe that
         | does amazing coffee has an RO filter.
         | 
         | I have an ECM entry-level machine and it's great. I dont' need
         | (or ever use) the frothing parts unless we have guests but they
         | do the thing they are supposed to and the main coffee bit works
         | great. I wish it could get a bit more pressure but it makes a
         | good cup of espresso if I tamp well and use nice beans (which,
         | you should always use nice beans. There's really no excuse for
         | that one).

         | 
         | i couldn't disagree more. there are many many differences
         | between a cheap (100$ is cheap) machine and an expensive one.
         | first of all, what is important is the pressure at the
         | portafilter, not on the pump, you would say that those are the
         | same, but they are not. second, it's important for that
         | pressure to be stable.
         | 
         | other things that are important:
         | 
         | - temperature stability. even small things like a colder
         | portafilter chan affect this, but what's most important is to
         | control a fixed temperature and deliver that across the entire
         | process.
         | 
         | - the quality of the filter basket (a precision filter from
         | companies like IMS & co). this helps with consistent extraction
         | and minimises the chance for channelling to occur.
         | 
         | - having a way to do a pre-infusion
         | 
         | - being able to change the temperature and pressure in order to
         | accommodate various kinds of coffee and tastes
         | 
         | - etc (i can go on for ages with differences, like dual vs
         | single boiler, milk vs no milk, rotary vs vibration pump etc).
         | it's like saying a ferrari and a ford are the same because both
         | of them have 4 wheels.
         | 
         | yes, you can make espresso without any of those, but saying
         | there are no differences is not true. with skill and an
         | expensive machine you can do a great espresso (or buy a Decent,
         | you can do that without the skill if you don't want mess with
         | changing variables, but still the output is great. with skill,

         | There is, actually, a lot of differences. Expensive machines
         | have that cheap ones don't:
         | 
         | - multiple (2+) boilers so you can pour 2 caps/pour cap and
         | steam/etc
         | 
         | - a lot less noise
         | 
         | - more consistent temperatures
         | 
         | - preheating
         | 
         | - as mentioned, more consistent steamers, but also precise
         | control over them
         | 
         | - built-in grinder (most of the times mediocre one, but better
         | than none at all, albeit most people who follow this hobby just
         | buy a separate one)
         | 
         | - sometimes they can be controlled remotely
         | 
         | - other smaller things
         | 
         | Most importantly, they're usually a lot more reliable and well-
         | built.
         | 
         | But yes, taste-wise difference will not be substantial, its
         | more like paying for your own comfort if you really want to
         | invest in coffee. Hand lever brewers can be just as good for a
         | fraction of a price if you don't mind to take extra steps.
         | Makes it more fun for some people actually.

       | If I were doing it, my design would consist of:
