Yeah, it seemed the Express Lander was too good to be true. I don't see how it could be so hard to design an ultralight liquid fuel stove!
I am currently using an MSR SuperFly and I like it because if I run out of canisters and I am somewhere that the canisters aren't available, I can still hook up a butane bottle from any gas station. I just don't want to be left without fuel during my trip, which is the only reason I am considering a liquid fuel stove. No fuel = inoperable stove = dead weight.
