Earlier quoted context omitted.
I own 3 espresso machines and have access to 5 no matter where I am (Splitting my time between Tel Aviv and the bay area) and I still drink coffee outside.
I find it's really hard to make a homemade espresso that comes close to the one you get from a café around here. But then again maybe I should invest 10k on a new machine (and then 20k to renovate my kitchen to fit it in).
Totally worth it though. The grinder (and coffee beans - buy them no later than a week after roast) are the most important part really.
