There are some decent camping cookware products out there now which are very light and very strong. If weight is an issue then those might make more sense.
If you are sold on cast iron then I echo e others who said Lodge. They make the best cast iron these days. There is better vintage stuff out there, but you will pay more.
GB is right on with the weight issue. If you're going to be using an open fire for cooking CI is great, but for a camp stove it's sure not a requirement.
