Query: Don't waste your money

I purchased this coffemaker brand new in December 2008. It performed well but was a major pain each day because the coffee grinder must be washed each time it's used. After a year, the filter basket door started popping open, sporadically, while the coffee was brewing, creating a major mess all over the counter. Now, I have to stand watch while the coffee is brewing. So much for using the programed brewing feature unless want I want to clean up a major mess when I enter the kitchen each morning.
