Hello all and thanks for adding me to the forum. I need a little help. I got 2 camp stoves at once in a bulk deal and I'm trying to decide which one to keep and which one to sell. One is an old Sigg Firejet and the other is an older Optimus Nova. Which one would be the best to keep? Both work flawlessly.. I dont have much experience with these so I thought I'd ask those of you that do. See pic for reference. Thanks in advance.
