Well, in spite of Slowcowboy's opinion I see way more double mantle green 220 and 228 models than 200As. It does not mean that they are rare, just far less common than the double mantle lanterns. I like my 200A because it is smaller, easier to use and seems to put out just as much light as the bigger lanterns. At least as much light as I want. I would surely prefer another 200A to another double mantle but I have enough of each.
