Hi, and welcome to the forum. Much depends on how much cooking you are going to be doing - if it is only the odd can of beans, and kettle then the suitcase types are fine. However, if you do intend to be doing a reasonable amount of cooking then these can work out expensive gas wise - in which case you are better off getting one which runs of a larger bottle - the type with two or three burners/grill.
The disadvantage is the space a gas bottle takes up.
My next cooker is going to be the Coleman dual fuel which runs on unleaded petrol - but they are around £80 - but for me the space saving advantages are going to make it worth while - two kids and myself to cook for.
Hi thanks for the advice, we went camping last year in a pre-erected tent with a stove and we cooked a full breakfast everyday and cooked tea nearly every night. I only have a corsa so space is limited.
The campingaz bistro style stoves are cheap and work quite well. If you shop around for the gas it can in fact work out cheaper than the campingaz (907) bottles. Space wise this stlye of cooker is great and much smaller than a full size cooker.
We have two of the suitcase type stoves and manage perfectly well cooking all of our meals on them for the two of us, I like the fact that I can take spare gas whereas I dont actually think I could fit a gas bottle in the car in the first place let alone take a spare one
