I find EZ-Cup the best solution, I use a little paper filter that fits in a reusable cup, and I get to use fresh ground coffee. Cost per cup is around a dime or so, and the cleanup is literally just pop the filter into the compost bucket. It may not be as good as an AeroPress, though I can't tell the difference. I find the fresh beans, quality coffee, and a good grinder are far more noticeable to me than press vs. drip.
