My previous "space maker" was probably just like yours with a square tank. I forget why I replaced it, but it was old and something went bad on it that I couldn't fix. The replacement was the style I recently tossed and at first I thought the resulting extra space under the tank would be nice. Unfortunately, with all the dripping, the only thing we kept underneath it was a cloth placemat to absorb the water.
I like the Gevalia with the thermal carafe that we're using now (we got it free many years ago with a order of coffee) but it only does 8 cups. It makes good coffee and the thermal carafe keeps it fresh, but it doesn't have a timer. I also want to keep it as a spare and as a "travel pot" when we go cabin camping, etc.
