I've used the MSR Whisperlite (blow torch) stove, Coleman Peak1, and the Optimus Nova stove over the years. The Nova is a nice stove. I've used it for 3 years. You must be VERY careful when uncoupling the fuel line from the bottle assembly. Unless the outer barrel clicks into place to close-ff the fuel supply, fuel will spew out all over the place. From now on, I depressurize the bottle first. I requested a new pump assembly and got one for free (!) because of the fuel cut-off hazard. This one had similar probs + the fuel line filter came off in the bottle and the line came loose from the pump. I do not have any recommendations. Optimus has a new stove for 2007:
