You have a few options including Chemex, Hario V60, Gino Dripper and Kalita Wave just to mention a few.
If sticking with the Chemex and brewing for yourself I would suggest the smaller 3 cup as it will retain heat better for smaller volumes of coffee.
I have a 6 cup with the wooden collar and it's great for 2 large cups of coffee. Picture of my 6 cup in background.
Between order and chaos there is espresso.
