I'm still using a Svea 123 inside a Sigg Tourist cookset ...

... a design tested over the decades.

I burn Coleman fuel.

I bought mine in the 1980s. I have used it on many backpacking trips, and one canoe-camping trip, and will use it when I finally get out there on a bike tour.

I don't think the Sigg Tourist is still available, but the Svea 123 is.
