I have one of those flush mount stoves in storage. It has a propane leak that I could not find. If you know how to repair this, I can send it to you for the cost of shipping. AND yes, they are pricey.
I would probably give it a try (repair), but I'm on the road until end of September. If RnK wants it, go for it. I'll check back with you in two months to see where it's at. Thanks.
