My husband is the coffee drinker, and while we do have a Keurig now, we don't like paying for the individual cups. He has a reusable cup that he fills with regular ground coffee, usually the Eight O Clock brand. He likes the taste of that just fine.
I am not a daily drinker but they are pretty good. It depends on what you like and what you buy. Not all of them taste the same and there is a huge price to pay when you compare the ones which are already made to the ones you can do on your own.
