I have a titanum cup - and love it! I also really like my titanium cookset. To me it is worth every dollar. I do not use aluminum cookware AT ALL. Ingestion of aluminim may be linked to Alheizmers.

I actually cook - not just boil water. In the past when I used aluminum, I felt they burned food more easily.

Now, to put it in perspective, these items were given to me as gifts. I always put the expensive UL gear on my Christmas list!
