The Specialty Coffee Association has a certification program and list of machines that have passed:

Units by Cuisinart, GE, Oxo, and Zwilling are on the certified list and can be founded listed for US$ 230. One of the main items for certification is getting the water consistently to the correct temperature.
Or you can spend $30 on a dripper and $50 on a (simple on/off) kettle:

With the difference going to a good grinder so you're making coffee with fresh beans.
