Look around. I know Mr. Coffee used to have one that you could set to brew at different times. Though, wouldn't it be cheaper just to time your current coffee maker once, see how long it takes to brew and then file that away in your head for future reference?

There are indeed Mr. Coffee models that tell you not only when they're done, but also when an hour has passed since brewing finished.

Cuisinart Automatic Grind and Brew. It beeps when it's done, you can program it to make your coffee at a certain time every morning on it's own, you can program how hot you want the coffee, different strenghts etc. You can also take the pot away midstream to put a cup up to it if your that impatient and it won't spill a drop. Plus, you can program it to shut off when you want it to.

Cuisinart makes on that beeps when it is done and beeps when the heat turns off under the pot. You can set it to 1, 2, 3 or 4 hours of blissfully hot coffee! It's great!
