Rusty,
One question that is probably relevant to the opinions being sought is what will be the predominant use for the stove.
If you are doing shortish stays (3 -5 nights) not too far from civilisation then I would go with a gas stove.
I have a Coleman 2 burner and it is great, very fast, clean and pretty efficient on gas use. Also you can get small canisters for short breaks or bottles for longer stays.
Over the Easter break I was in the VHC and enjoyed about 2 inch of snow fall and pretty cold temps. Had absolutely no issue cooking breakfast in the morning on the coleman and this allowed me to stoke up a nice fire to warm the kiddies up rather than playing around to get a good cooking fire. I did cook over the fire for dinner which is my preferred method but everyone but me was pretty cold.
I have a small MSR backpack style camping stoves, again used regularly in very cold condition on back counrty skiing and camping trips and the like and never had a problem with the cold. I think you have to be dealing with temps much lower than we get to really be concerned about the performance of gas stoves.
I have in the past used metho/kero style back packing stoves and they are great but very slow.
I have never owned a dual fuel style but have been with mates who have then and generally I find the burning fuel is not the most pleasant thing to cook over. However if you are doing long trips in really remote places or at proper high altitude then they would be a great choice.
Hope this helped.
George
