I got an Esbit type stove on eBay for < $4 shipped. Came with fuel tabs. It had some rust but appeared unused. Maybe east German surplus. Have not tried it yet.

I saw a youtube video that showed a $2 Esbit type stove that th reviewer found in some kind of Canadian dollar store. If I had seen them I would have bought a handful.

There are a bunch of canister stoves on eBay for < $10 shipped with igniter that look interesting. I have not pulled the trigger on one yet. Not a big fan of canister stoves. Just do not like the canisters.
