For years I used a 1,5l Trangia pan and a simple plain 600ml s/s pan with no handles, but it also worked with a Trangia pan grip
I never got the hang of a meths burner, so I used them on a gas stove
I don't know what was the make of the s/s pan, I found it just loose in a camping shop sale years ago
I was happy enough with the s/s pan, so as far as i'm concerned there's nothing wrong with s/s for a backpacking stove
I used that combination for years, but then I wanted something a bit lighter, so I got an HX pan set from Go Outdoors and it's excellent
I'm not going to get bogged down in the mental arithmetic of whether the extra weight of an HX pan is offset by the weight of the fuel savings.
For that size of pan the difference will only be a few grams either way
But the increase in efficiency and therefore the reduction in boiling time is very noticeable, and i'm now fully converted to HX pans; I'll definitely choose HX pans in future
That pan is aluminium alloy and still available; in a sale at the moment. It includes a small pan lid, just enough for a brew -
Go Outdoors OEX Sola - X £19, which is a very reasonable price
Search YouTube for 'OEX Camping pans' there are several reviews
Otherwise Search t'Net for heat exchanger camping pans. I've seen them on Ultralight Outdoors; Backpacking Light; and Amazon; and probably other suppliers as well
