I got a great deal from a local retailer on the burner component of the Primus Eta Express, because the rest was damaged in shipping. I never liked the charged canister stoves; it always seemed like an explosion waiting to happen; and they weren't available in some of the places I traveled.

This little burner has converted me!

It light, fast and a single small canister has lasted me 3 weekend trips so far. If I were traveling in the developing world again, I'd want to be sure the canisters were available there, but for everything else this is my choice.
Primus has a little lantern I like the look of also.

The one downside: if it stops working, there is nothing I can do. With my old Whisper Light International I could take the whole thing apart and fix whatever went wrong. I don;'t see that as a possibility with the Eta.
