I have used the campchef a few times and it is a decent unit, especially if you consider the price. The shut off valve is a little weak IMO. I bought my first portable campfire about 10 years ago, it had a aluminum pan with legs that folded up and was made in Utah but haven't seen another one like it in awhile,so I don't know if the company is still around or not.
I replaced it last year with a Campfire in a can which is the nicest one I have seen/used. I really like the way it stores with a lid that snaps to the base, which protects the hose/regulator very well. The lid also acts as a base which raises the fire up higher off the ground than the other units I have used. It also has the best shut off valve and is just better made overall than the others I have used. The down side is the cost of course, but the wife loves it and I was able to justify the cost.
Don't have any experience with the little red unit.
