espresso machines are maybe in a different class of "coffee maker" but it seems like even the cheapest of those is pretty easy to service/repair/source parts.

or in some cases even upgrade to improve capabilities...

I did the gaggiauino mod to my gaggia classic and basically everything in there is just pipes and wires... the most complicated single part on the original is the vibratory pump. I'm pretty sure i could keep that same machine going indefinitely with access to parts.
