I'm beginning to plan a long hike of the Camino de Santiago and the LePuy approach trail next year. I currently use an MSR reactor, but I am concerned that I won't be able to find compatible canisters while in Europe. I'd rather not buy a Gazbleuet stove which will be redundent as soon as I get home unless I have no good option. Can anyone tell me if MSR compatible canisters are readily available in Europe?
