I've had whisperlite stoves since near the beginning. The new internationale is quite robust- the shaker jet makes all the difference. As DD notes they don't simmer very well, but they are good at throwing out efficient btus. Wire legs won't be a problem if you use the heat reflector they sell with the stove.

A year ago I picked up a canister stove- MSR pocket rocket- much quicker and easier to use. really small and light but difficult in the wind and close to useless if it gets cold.
