can anyone recommend a campog cooker/stove? For the past few camping trips - and camp bestival last weekend - we have used a single burner job, which has been OK, but from looking around at other people's set ups, we have decided we really would like to get a double burner type affair. or, at least, a more stable thing (our single thing got blown over in wind and set fire momentarily to the grass!). Have been looking at the campingaz products, but not clear on the extras (ie fuel) that needs to be bought? very very grateful for advice!
