Query: I LOVE the idea, but my machines keep breaking!!

I love the idea of the Keurig brewer. My husband and I drink different coffees so this is a geat appliance for us. However, I have been through 2 of the B70 brewers. I always take care to descale and properly care for it, but it is the most fickle machine ever. Customer service is always helpful, and they can usually get it working again.. but, who has time to spend 30 minutes on the phone with customer service once per month?!
