For the past 5 years, I have been using the Black and Decker Brew-N-Go which makes a 16 oz cup of mil-spec coffee. They come with 2-year warranties and the mfg. stands behind them. My first machine had an issue and the mfg. replaced it. I've been running this replacement for the past four years without issue. I did buy another just to have as a spare but it may be a while before it's needed.
