Yup!
just like INSAYN, I picked up three from CL, in one Saturday afternoon all for under $50 total. I took them all apart thinking I'd build one good stove and have leftover spare parts. Turns out I cleaned them up, put them back together and they all worked beautifully! The only difference I could see between the duel fuel (silver tank) and coleman fuel (red tank) was that the duel fuel has a stainless steel generator tube. I kept that one and since the other two were clean and working, I sold them for $50 each on the CL, doubling my money and getting a free stove out of it. NOTE: Everyone I know with a red tank stove has used gasoline in it with no ill effects, so you definitely CAN use gas in a coleman fuel stove when necessary.
I also don't bring extra fuel for weekend trips, the tank on both the stove and the lantern is more than enough for two evenings and two breakfasts. I used to use a red 20oz. MSR bottle for extra fuel. I went on an 8 day trip one time, so I skipped that and just brought the gallon, and just kinda stuck with the gallon since I got used to packing around it.
I neglected to say it in my first post since I agreed with Neil D., but backpacking is a whole other animal. There's no reason to use backpacking gear when you're car camping. I honestly don't recommend backpacking with small children either. They have all the common sense of a chihuahua and they prove Murphy's Law every time you blink. My wife and I both used to be avid through-hikers (I use that term because "backpacking" is often used to describe college dropouts experimenting with homelessness

) These are the stoves we used:
I liked my liquid fuel because it didn't add empty fuel containers to the trash I was hauling around, and one tank would boil water twice a day for a week straight. But my wife's Firefly is definitely lighter, smaller, and cooked faster (light it and cook, mine I have to let heat up until the flame turns blue). I don't think either is adequate for car camping. Backpacking stoves are benchmarked by how fast they boil water. Backpacking you eat food with high energy density and minimal prep (like freeze-dried dog vomit labeled "Lasagna"). That's no way to eat if you don't have to.
As for the "hairspray stoves", as an engineer I really don't like them. They are banned in a couple of countries (Australia most notably because they were hugely popular there) because they explode under normal use and without warning. I'm not your momma and I'm nobody to tell anyone else how to live their life, but just do your research before you buy one.
