There are a number of models and makes on the market (I was recently impressed by my neighbour’s stove which collapsed flat into a case little wider than James Bond’s attaché case in From Russia with Love – it even contained a pop out dagger, OK it was actually a filleting knife, but equally as effective!).  

The key to success is the presence of two rings and a grill, so as long as these are available and you can’t smell gas when you’re cooking, then whatever model you decide on should be able to produce the goods.  None of the recipes here involve hours of simmering on a low heat, so your gas supply should last out. The big blue Gas bottles are rather expensive when you first purchase one, but a large chunk of the cash is a deposit, so when you come to buy refills the price drops to about fifteen quid.  The only down side to the big blue bottles, is that it is really difficult to gauge how much gas is left in the bottle from last time you went camping.  I guess it’s an art and the more camping you do the better at gauging your gas you become.
