I started a new job, and they have a Keurig coffeemaker. It seems pretty convenient, and I see now that there is a refillable filter cup so I wouldn't have to purchase those expensive k-cups if I didn't want to. So I'm thinking of getting one for home. I looked at a few in Kohl's last weekend and the less expensive ($100) ones look like cheap plastic crap, while the substantial ones are well over $200. Online reviews of many models seem to indicate trouble with needles clogging and pumps breaking, so I was wondering about the real-life experiences of people on this board. Are they worthwhile spending the money on? We would only use RO water in it.
