M.P.
I make single cups of good coffee using a drip system. You can get a cone and filters for single or two cup coffee. Melitta is one brand. I found my cone and filters at a grocery store. I bought the single cup size first but found it didn't work easily for a mug. The two cup size is perfect.
We use a french press for multiple cups of coffee. It's still a hassle for just one cup. You end up having to clean the pot, while with a one or two cup drip system you only throw away the filter.
