Got the Camp Chef Flame Tamers. Gawd, what a difference! These things are really worth the money!
With this stove, even on low it is still just a tad hot for simmering something like a chili for hours, even with the flame tamers, but very manageable for sure. In any case, I still long for a valve that you can turn to just about the "off" position, or as low as it will go... In years of brewing, building breweries, designing propane gas systems, I have learned that "low" is mo better, even if it takes longer.
I love this stove none the less! Great quality. I am a happy camp chef camper now, but it can still improve. After all, when you can boil water on the lowest setting (albeit a function of time), that ain't low enough to gently fry and egg sunny side up on my CI. Even with the flame tamers, I was able to fully, and fairly quickly cook bacon and eggs this weekend, but I had to stay on top of the process.
I have found that an old adjustable regulator fills the ticket pretty well. I changed out the stem with the stem from the camp chief regulator.

Although this regulator in combination with the affixed gas valves on the camp chief will allow it to get VERY low, still, I long for a good zero to nothing shutoff valve such is on the trusty Coleman stoves.
Overall though, I likey!!
