The main limiting point with nickel is that is an allergen. It is
perhaps the most common cause of contact dermatitis from jewelry. So
having pans lined with nickel is begging to give someone a belly ache.

I'm not really concerned with the lining material. It's been discussed
a fair amount in the past, and I think know enough in this area. It
would be nice to know more about how the construction of the pans
compare, ignoring the lining material for the moment.

Thanks,

John
