OK yes I would agree 80 a tube is not out of the question. But it is very rare that they need replaced so the price really doesn't mean much. I believe there may be some manufacturers who charge that much for a baffle but most do not. I have never replaced one that cost that much. And unless you abuse it there is no reason it should need replaced more often than 10 yrs.There is more than one and it’s unprofessional to name them. So I won’t. But according to the companies price sheets, there are 4 tubes and retail price is $80 per tube. Another example is a baffle plate for a top seller, $316.00 for the kit. There are dozens more.
The point I was making is what I posted earlier....not all cat Stoves are alike....not all non cats are alike with regard to quality, durability and the ability to maintain clean burning.
