Been using an MSR pot set for almost 18 years now. It was a little pricey but I'm pretty sure I've gotten my money's worth. In total it's three pots that nest together. Not a bad setup.
I also have a pair of MSR pocket stoves - the Dragonfly and the Windburner. Both are great little stoves. I am shying away from the Dragonfly to negate the need for an additional fuel type. The Windburner is their version of a rapid boil stove but unlike on the others on the market it can simmer.
I used to carry a dual-burner Coleman stove but, as mentioned with the Dragonfly, I'm moving away from it to get rid of liquid camp fuel. I did like it because I can use the cast iron skillet and a pot on it at the same time. However, I no longer need the skillet because...
Skottle. It's pricey, I know, but it has really simplified my kit. No big bulky stove. No bulky cast iron skillet. Just a big bulky skottle. I like that it's free-standing (unlike my stoves) and that it runs on propane (so no liquid camp fuel like the Dragon Fly or Coleman two-burner).
So... right now I carry the Skottle and Windburner along with the MSR pot set. If/when needed I can use the burner from the Skottle to boil a large pot of water (to clean or or cook with) when needed but so far the Windburner has done a good job at that.
I've debated about a small single burner propane stove. Something I'll be looking into this winter for next year's travel season.
