Hi, I love threads like this! Let me be honest I am the worst kind of person a kit freak who seldom camps! Over the years Ive collected so much kit it is embarrassing (but never paid full price), but I love it all. I have, MSR petrol, Trangia (plus gas conversion), Mini Trangia, Gas, Green gel, Kellys Kettle and Hexy. They are all good and bad in different ways.
The MSR, I wanted one from being a kid, I love it. I find the idea of pressurised petrol 9 from a naked flame terrifying but it works well. I find having to preheat it a pain as it gets very sooty. It is very hot, but too hot to cook things on sometimes try simmering something!
The Trangia is very good; you feel part of the in crowd in the lakes. But meths feels expensive even though it isnt. Everything gets a bit sooty, but not as bad as you do handling an MSR. It feels very bulky, but then you should compare the alternatives in conjunction to a wind break, two pans and a kettle.
The Gas conversion just works well, but it all seems to be a bit of a palaver!
The Mini Trangia is really quite good and I tend to take it with the big one to have two burners on the go.
Gas, boringly efficient. The VW of the stove world.
Green Gel I got a Crusader cup and stand for Christmas and some gel, not impressed, still not managed to get a mug of warm water to a boil even inside!
Kellys Kettle It was a present and I dont really use it, it just seems to get so dirty and is bulky. I suppose it looks great in a Range Rover or a by a salmon stream with a black lab. It works well with a coke can meths burner in it though!
Hexy, I loved when I was a kid and I dont know why I dont use it more. Not high tech enough I suppose. I think it is because I dont have a feel for how much fuel I would need for x number of days. But if you consider weight, size, cost and effectiveness its difficult to beat, so I dont use it.
So all in all, go to the chippy!
