 There's the international multi-fuel stove. I think there's even a universal stove, so you can use your multi-fuel, and then you can switch the adapter and put on your isobutane adapter to run that as well. And then there are the Crux stoves. Those are made by Optimus. That's actually the stove that I use is the Crux. There's the Crux Lite and just the classic Crux.
