$450 is the list on the 3.5" X 18" X 3" catalyst for the Xtrordinair. I typically cut my customers a break to $399.
Replacement is very simple and it will last quite well. 10 years is often promoted as the life span but I would figure on changing it every 7 to really anticipate what you will need in the real world.
You're certainly right in estimating the chimney savings alone will pay for MANY catalysts. By the time the catalyst cost uses up that savings you may be too old to handle the wood anymore anyway.
