I was just on eBay for something else entirely and saw these images next to each so I screen-captured them as a PSA:

If you want a 0.9 ounce canister stove that is short enough to work really well with a Moulder Stripâ„¢, but isn’t the best with large heavy pots, go for the one on the right. Â If it looks at all different or the price is much lower, just skip it.
Do NOT get the one of the left, even at $5. Â It’s 3 times the weight, conducts a LOT of heat down the valve stem – enough so that the valve geometry changes after 2 minutes and the gas stops flowing. Â I wrote up more details on that last year but am stuck at home and thought I’d repeat myself.
