It that the Brunton Optimus Nova or one of the other models? The Optimus burner look nearly identical to the DragonFly ... but you've got to love those swing out feet.  And its not like you're going to damage the pump on a trip ... one of the few that's nearly all solid metal! dd

Yup, the Optimus Nova.  Still noisy, but somewhat quieter than a Dragonfly.

My Dragonfly constantly clogs which is why I replaced it in the first place.  Field-stripping and cleaning it on a nearly daily basis got old fast.  When it's running right it's a great stove.  Mine's got to be defective somehow because I know many others have had great reports on them.
