If the burner is used with the trivets from Backpackinglight ( http://www.backpackinglight.co.uk/bushcraft/RE103.html) or 3 x 4" nails as a pot stand its easy to use a Crusader with just the Trangia burner
... I investigate fires for a living ...
I've used all manner of stoves and have an unhealthily excessive collection of them...but if I'm off for outdoors for a while (more than a couple of days) I always revert to the swedish army trangia set (includes pots, windshield, meths bottle etc). Meths is available virtually everywhere across the world and the pots (buy steel, not aluminium) are bombproof. For about £15 what could go wrong? Sure its a bit bulky, but like I said, having tried most everything else I always come back to it. As posted above, if you are going to use the burner on its own, this won't be the solution you are after - you definitely need the wind shield most places. Having said all that, do try making a side burning stove like the white box or a derivative of it - you'll learn a lot from that. Just don't put petrol in it - I investigate fires for a living and petrol is not worth playing with! Enjoy!
I have exact the same set as in this review:
http://www.bushcraftuk.com/forum/content.php?r=284-Trangia-Triangle
The Triangle is lightweight, packs very small and can support almost any pot (zebra, cups, pans,...)
However, I won't rely on it for real cooking, brewing some coffee, OK, but having a meal like rice, beans and meat is quite hard to do when wind gusts pass through camp.
I used the set in Ireland (January 2014) and I was only able to get some water cooked inside my tent.
And don't use alcohol-gel of any sort, this will give you a rather lousy flame. Liquid alcohols give much more heat.
For quick brews yes, for big meal-preparation, gas-stoves.
Good luck!
Would have to disagree with your final sentence there, the best stove I have found for cooking 'proper' food is the Trangia, in its 'proper' form. however, if you wish to take bits of it away and try and use the burner with different pans, or without the windshields that were specifically designed for it, then its not really being used to it's optimum efficiency.
A big NO to petrol... they're designed for alcohol based spirits like meths, ethanol, whisky, vodka etc
You can build a stand for them if you want but most folks use them in conjunction with something like a click stand, honey stove, hobo stove etc.
They can leak fuel over time, it's best to keep the fuel separate and fill them each time you need them. Note that if you need to fill them after using once make sure it is cool before refilling and lighting.
You can use them from a crusader up to a large billy like the 14cm zebra, obviously it takes longer for the larger sizes to get to boiling temperature.
