For the price the Trangia is an excellent buy and there is no issue finding fuel (yellow heat)... I have one kit with the supplied cooking pot and combined one with a vintage mess kit that came with a base / wind guard. Everything (save for a small fuel bottle) I need can be packed in here including a fair amount of food (packaged soups and cliff bars).
Takes about 4 minutes to boil 3 cups of water...
For bigger groups, car camping, or when I want a little more cooking capacity I have a SVEA 123 and SIGG kit... it is a beautiful thing.
You can't buy the SIGG kit anymore but they are available on the grey market.
As it is self priming it gets a little black at the cup and this boils a pot of water in about 4 - 5 minutes... you can also stack the pots to make a double boiler.
