Won't help now, but hit the garage sales next year and pick up a couple of the old glass lined Thermos bottles. Your coffee will stay hot all day, and then some. As was said, if you drop it, it's history. That's why you buy two and get em cheap at garage sales.
The Stanley's are about as close to indestructible as they come. As was also said, pre-heat them and they hold up really well. Another thing that can be easily found and picked up cheap at garage sales if you do a little scrounging.
