im not a light backpacker either i buy from who ever has it cheapest.
i got my eta solo stove for 72.00 shipped from fedtactical.com because amazon wanted more. it was also lighter than a jet boil solo and also has a coffee press option.

i read reviews, ask questions and buy the lightest best gear i can find for the price im willing to spend. this year im having to buy everything from a to z because i haven't been in the wood over night for years.

i say get it where you want. because ultimately you get to carry it. just take your time and do research.
