I must admit I take the extreme minimalist approach, boil a mug of water, add two teaspoons of ground coffee to mug off the boil. Leave two minutes. Stir (very important, makes all the gunge go to the bottom for some reason). Leave 30 seconds. Drink.
Apart from the last half inch in the mug, this makes a perfectly good cup of coffee with no other apparatus necessary, and the grounds can just be chucked on the ground.
