Well, if you're handy in the workshop, should be OK. Zandor's looks fairly mechanically stable.

I'm only planning one alteration to Z's work- will be using silicone sealant instead of self-adhesive foam on the tube ends where they meet the sheetmetal. I think the foam would degrade from heat & UV and might indeed become loose. Silicone is an instant rubber gasket which will handle 500F all day for years.
