Query: Great grinder -- for a few months...

I loved this grinder when I first bought it. That it has an espresso doser was a big plus. And for a few months this was a great little machine. Soon, though, grounds started jamming up the burr. Then, when grinding fine coffee, it would block the exit into the ground coffee receptacle. It seemed like I was taking the thing apart every day. This caused the bean holder to crack, and now it's unusable. I guess I could get some of the parts repaired, but for ... bucks, I would expect a little more than 3 months of trouble free operation. Fortunately I have an old blade grinder available while I search for a really good, sturdy burr grinder...
