I assume he means a Chinese, screw-on canister stove such as:
$8.23 with free shipping.
or any of many others if you search a little on ebay.
Not the lightest option or the best made. But you seem focused on cost and it would be a way to simplify and reduce cost on your white-gas winter-camping option. Also, I'll point out that a white-gas AND a canister stove puts out more heat (when both are operated) than any multi-fuel stove does by itself.
Edited to add: that $8 stove doesn't allow inverted operation. I've gotten some of the cheap stoves for school trips and to scatter in the emergency gear bags in the car trunks (I live in Alaska, it is -24F right now).
