Espresso maker or Keurig (bring your own K-cups)?

Stick with a Mr. Coffee type maker, a cafetiere/French press, and local pre-ground coffee.

Ditch the espresso maker – IMHO espresso isn’t that ‘big’ these days.

Any “cups” are going to be too expensive to import, and not good for the environment; and re-useable cups will be the primary things stolen from your listing.
