I used one of these for years and they definitely get the job done at a low price point. The bag works for hauling gear well enough. The frame is not too heavy and it's strong and comfortable enough.
I think this pack and bag is the #1 option as an entry level pack, then find out what you do...
I have used a Jetboil canisters to boil water in sub-sero temps on open tundra with wind. This would probably work with any burner if you buy the 4-season fuel, you just have to block the wind with something body/pack/snowmachine etc.
