You don't need an expensive coffee maker to make a really good coffee. A plunger ( also called a Press pot) will do just fine if you follow some rules.
Over a latte at Columbus Coffee in Albany (run by Danny and Tracey Wrigley) I learnt some of the finer points.
Just before making the coffee I swirl a little hot water around in it to prewarm it. Then I add the ground coffee.
If you make more than you need do not heat it up again later in the microwave , keep it hot in a thermos or freeze it in ice cube trays for your next iced latte.
