The only problem I ever had with my Svea was that everyone tried to sneak it into their pack. <img src="/forums/images/graemlins/wink.gif" alt="" />

It was a great stove. I finally gave it up when the Simmerlite came out, since I value lighter weight. However, aside from lighter weight and greater stability with larger pots (1.5 and 2 quart MSR stainless), the Simmerlite didn't perform any better or worse than the Svea. And yes, you can simmer with the Svea.

I eventually replaced the Simmerlite with a canister stove (I no longer go out in the dead of winter.)

No, you're not nuts to consider it - especially since you realize you'll pay a price in greater weight. But mine never needed maintenance (except running the needle up into the jet to clean it), and never failed to light.
