I get my own bean, and I use a burr mill grinder, really nice one, and I use a Keurig, EZCup reusable filter holder, and ecobrew filters. Because it makes a pretty descent cup of coffee, in about a minute with no cleanup required. I've tried percolators, french press, open drip, and aeropress, and they all have uniqueness's, but to my pallet, they aren't so good that their worth the convenience. Cleaning an aeropress 7 times a day starts eating into your productivity faster than reddit.
