It's become impossible to find a coffee maker where water doesn't come into contact with plastic. There used to be a pretty decent one: Gourmia GCM4900. It had some subtle design flaws, and only lasted 5 years. (If I can buy another one, I probably can somewhat mitigate that and make it last longer)

I use a moka pot. No plastic, no filters to replace. Great coffee. Takes a little bit longer but it's worth it.

This comes close to no plastic:

There's a silicon gasket, and they offer a stainless steel plunger upgrade. There is some plastic in the portafilter that coffee will touch (unless you run in bottomless mode).

The bigger problem with most espresso makers (but not the model I linked) is that they use brass for the heating block / boiler and that leaches lead into the water.

This matters less in coffee shops (where they use up the water in the boiler in a few hours or maybe a day), but a lot more at home (where you might only refill the boiler once a week or even once a month).
