Query: The Best coffee maker

I guess I became accustomed to having great coffee, until the warming plate on my Bunn left my 2nd cup cold. I tried cleaning out a Mr. Coffee machine that was in storage. Big mistake. Bitter taste still in my mouth from this morning from the Mr. Coffee machine. Never had a bitter taste from the Bunn. I will just have to see if the Bunn can be repaired, or buy a warming plate, or a new Bunn.
