I've been using a heavily modified US Stove 5660 for 11 years now. The first thing to die was the igniter and burn pot. I made the new burn pot using .250 inch thick metal sourced from a scrap yard metal dealer nearby. See the enclosed photo. The igniter was done away with. I just start the fire manually. It's now going on 4 years with no warpage. The rest of the stove has been upgraded as the garbage motors soon got noisy. Enjoy.
