Query: Not strong enough for long term durability

I completly agree with the first reviewer - the coffee maker itself is great. Its simple, inexpensive, long lasting, and makes good coffee. But the carafe is too weak. It should be made of strong pyrex glass, but instead it seems to cracks too easily. My first carafe cracked after about a year and I ordered this replacement. I was always very careful with the second one, but after about a year, it cracked also. Now I am ordering my third one. I am also like one of the other reviewers who said he refuses to buy another coffee maker out of principle. I don't like metal carafes because you cant see how much coffee you have left. I feel like I'm buying a new coffee maker each year. Its almost like the business models with ink-jet printers - sell the printers cheap and kill them with the recurring cost of ink. Here, its the recurring cost of the carafes.
