If that's a Gasmate one I have the same,also runs off a cheap propane Canisters with another screw on connection.Been testing it for about a year to write a review on it.It's been great to be honest and cheap to run.I like the option to use the canister that's in your picture as the others don't work at certain altitudes and weather conditions.
Also use the Iprimus 24000btu,it's a wicked unit,use high if needed and down to a simmer when required....I'll write a review on it also..
The one in the link is similar to my hiking/kayak setup. One of the beauties of the little isobutane cannisters is that they fit perfectly inside the pot set so less room is needed. The other is the amount of heat it puts out. Yes in cold/altitude the iso mix is much better than the cheap butane - apparently haha - not a theory that gets tried out in qld too often. There is a hose setup you can get for mountaineering to make it work more efficiently again but I don't think I'll ever have to worry about that sort of thing.
