I've found the cheapest possible automatic drip machine (small, the only interface is an "on" switch, probably one at your local Goodwill right now for like $5) with middling grounds (something available at Costco, not your fancy local roaster at 3-∞x that price per ounce) produces significantly better coffee than Keurig. Used grounds can go in the garden, and the filter's paper. Less counter space than a Keurig. Can smash one on the ground in a fit of rage every couple months, replace it, and not notice it in your bank account. Bag of coffee and box of filters take up less space than enough kcups to make the same amount of coffee. Unless you're into the flavored stuff. It's no help for that. Maybe look into cold brew? Cheap, low-equipment, tastes great with a splash of milk. Or keep Keuriging if it's making you happy, obviously. I'm just some asshole with an opinion, on the Internet.
