Now it is I have both an MSR Whisperlite and an ancient Trangia, to report they are both excellent stoves, but each has their advantages and disadvantages, where it was in my mind to combine the two, to make what I would call the ideal stove. So I looked into creating a conversion so I could also run the Trangia on cheaper to purchase and use pressurised Paraffin, to have found I would need to find an Optimus 'Butty Box' paraffin stove to provide the parts necessary only to find old Butty Box stoves had suddenly become collectable to well stuff up that idea as I was skint at the time hence the need for a cheaper fuel.
A few years later I had discovered Trangia had done just that, to create 'add ons' that would enable the design classic that is the faithful Trangia to run on other fuels including gas, so if I want to revisit that past idea again, it will at least be easier this time around, but just to alert you to the fact these days they don't just run on meths.
The benefit of the Trangia is that it uses about 90% of the heat produced by the burner to cook the food, for not only does it apply heat to the bottom of the pan, but also the sides and if one uses the 'frying pan' as a lid that other 10% or less is also utilised in the heating, so, they can cook food quickly thus saving fuel. In addition the Trangia comes with it's own windbreak, burner support and integral pans to perhaps only suck in terms of bulk and/or weight
The MSR is just a multi liquid fuel blow torch albeit a well designed and built reliable blow torch applied to the bottom of the pan and minorly the sides, but one still has to carry pans and a windbreak.
My next stove of which perhaps I will get next month will be a Stainless 'Wild Woodgas' stove so in terms of fuel I can use contained woody material to create flammable gas as fuel or I could use my Trangia meths burner in it, as my outdoor cooking needs have changed.
And of course the Trangia meths burner is a cooker in itself.
