However last year I got a Gaggia espresso machine, and espresso is a whole other world of complexity. My Gaggia only has the pressure mod, but I did plan to add a PID to it. It's still simple, turn on and let it get hot, then I usually do long pulls for like 40-50 seconds on a double shot portafilter. But there are other espresso machines with more electronics that feel desirable.
Of course I chose getting a Gaggia by going to Github and seeing which espresso machines are developer friendly. :)

However I just make coffee for myself. Maybe a Keurig is easier if you have guests. It seems most of the people I know who have it, have it for that reason.
If things get real bad, the Wood stick camp stove that’s just folding metal plates.
Propane burners are just an annoying in between, but our outages are rarely long.
