I have just taken delivery of a 27UL with kettle, not too expensive at £45.
I have bought it for a French trip where I can just pick a litre of alcool a bruler off the shelf in Carrefour for 1.60 Euros when buying my other supplies. Compared to buying gas cylinders it will have paid itself off in a few trips!
Last year I took my old primus but it also needed me to carry meths for priming and lots of spare paraffin (plus heavy trangia fuel bottle to enable clean filling), plus ti kettle and bowls. The Trangia works out lighter even without carrying two weeks fuel.
I tried boiling 600cc of water on both stoves and both used 16g of fuel (plus 4g of meths for the Primus) though the Primus was outdoors and the Trangia inside. I had thought it would use much more fuel than the paraffin stove.
The pans were called 1L pans in the blurb that I read, they are only 900cc and I wouldnt like to use them with 750cc in, 600cc is a reasonably full pot.
I think the kettle will remain at home, it is reasonably full at 450cc.
I will also be much happier to use this inside the tent on rainy days, I had to take the paraffin stove out each time or in heavy rain in an open porch trusting the volume of water to prevent the fabric catching easily.
My cooking is normally of the adding boiling water to couscous and heating tins of ratatouie etc style backed up with plenty of raw fruit and veg. The Trangia may make me a bit more adventurous as I will have lots of fuel to burn and it can simmer.
I do like the French boil in the bag dried pulse and grain mixes, even if I cant remember what they are called.
A question for Francophile-Trangiaphiles the Carrefour Alcool a Bruler has 90 written on it, does this mean by any chance it is already diluted with 10% water? Je ne parlez pas Francais.
Being tight as a Yorkshireman (Cardies being the Welsh equivalent) I will probably bring a gallon or two back with me from France as it costs too much here.
