>>2050123>and learn to refill your fuel canisters with butane for cheapMah nigga!
Near me the 235gr bottles are 1/3rd of the price of a 245 gram canister. (2.1€ vs around 6-7€)
Got a bottle to thread adapter and a thread to thread adapter with valve. (I can find 450gr threaded canisters reasonably cheap, 5€, but hauling a 450gr canister is a bit dumb just to make a coffee or a quick meal)
I originally had gotten a tripod adapter that does bottle to thread directly (picrel), but our magnificent chinkfriends from eBay seem to have shipped it to me on the back of a chinese guy on foot so it hasn't arrived in nearly two months. So I can't vouch for how useful the adapter actually is, the idea seems reasonably solid.
