<p>I think you are being very nice to buy a coffee maker for guests. In our house we have a drip machine, French press and a melitta drip cone.
In your case I would consider the guests. My Mom loved her coffee but she was happy with a percolator and Folgers. She would never have liked or figured out how to use a French press. I know they are simple but when you think coffee is fine served in a styrofoam cup you won’t care if the coffee is from a Mr Coffee.
When I am a guest I drink what my host is providing. The one exception was when I went to my MIL. The younger generation would bring their own coffee. MIL now has made the switch from MJB and we are all happy.</p>
