No Limit Expeditions while cooking for 20 people. Their low simmer is great and the sturdiness of the setup is great when compared to other similarly prices stoves. My only complaint, is that it doesn't do 34,000 BTU's like it's big brother - the GS-1000.
I know people who travel with two of them because they pack smaller than a traditional two burner like Cook Partner or Coleman. If you cook large meals or for large groups, the only drawback could be that the stove doesn't use propane. However, in my years of travel cooking for a handful of people or semi frequent use, the IsoPropane canisters shouldn't be a problem.
Let me know if you have any other questions. We'll be posting some specials in the For Sale thread in the days ahead - keep a look out.
