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

Some of the stainless steel French Presses are “insulated” by having glass in their layers so could be breakable like the old thermoses but there are some that aren’t and are all stainless and are cheaper too than the insulated. I’m realizing that being able to replace something when it breaks is probably the main issue where you are and not so much the cost but availability.
