I havea Gigastove, great stove, but I never use it:
For trips where I want/need to minimize weight, I use an alcohol stove or esbit. For trips where I don't (car camping, overnighters, canoe trips, etc) I use an MSR Dragonfly. I really dislike having to buy the canisters, and having a pile of half-full canister sitting around. White gas and alcohol (I use methanol) is cheap and you can refill your own containers, that aspect of both fuels is a real selling point for me.
For $75, I think a free-ish MYOG alcohol stove, and a used MSR whitegas stove cover all your bases: you have a lightweight system, a winter snow melting system, a large-group system, a car camping system.
Just my two cents.
