I've never had my own expensive home espresso maker, but I did work in a coffeeshop for three years and I do appreciate a good shot of espresso (or two).
I'm not sure you're looking for suggestions, but I do just fine with a
Moka - an Italian-style stovetop espresso maker.
I bought mine on Amazon (a four-cup... I had a two-cup that I bought in Italy but now DH likes a bit once in a while even though he
never drinks coffee) and the grounds are easy to get at normal shops here. There's nothing to plug in - it just sits on the burner. It's easy to clean up (no soap needed so the oils condition the aluminium to avoid any metallic taste) and makes good coffee. If it's too strong for guests, I dilute it with some water or milk for them.
Of course, you can get proper home espresso makers here if that's what you want to stick with.
