Query: Worked great until old age crept in.

I bought this in December of 2009, and it has made the best pot of coffee since then. This is important, since I have a pot every single day of the year (with rare exceptions). I have never used the programmable features of any coffee maker that I have owned (for many years) as I would rather keep the coffee grounds fresh until needed. After trying many expensive ($100 plus) and inexpensive ($29 minus) I would say this has been the best designed (water tank, coffee basket, etc) and made the best coffee. However, recently it has been "gurgling" more and more, and has now begun to give the "all done" signal before the pot is even half-way filled. It is 2 years and 3 months old, so I guess this is it's life expectancy. If it had lasted longer, I would have given it 5 stars.
