Having rebuilt mine, I would not hesitate to build / rebuild
your own. There are a few guys who have built their own, and have posted lots of info / pics on how to do it. A heavy duty stainless pipe, and the stainless tangs / framework inside could be cut and welded for a decent price
I would cut the old one down the middle, saving it for a mold
, or to epoxy
back together, after replacing the stainless stock and framework. Foam inside, and multiple layers of cloth on the outside to hold it all together.
Once cut open, see what size / guage stainless everything is, and go to a bulk / scrap metal yard, looking for 316 stainess.
Coudl be done for a few hundred bucks. And you will know what you have, when you are done. I welded in lots of extra tangs / gussets for strength, while I had mine open. Only cost some scrap stainless and a few welding rods.
