Mossback, Jetboil keeps offering upgraded models. If you haven't looked at the newer models check them out too. I have the original and it lacked much of any simmer control. The newer ones are better at simmering, even though I don't do much but boil up water to dump in a bag, I got one none the less.

One thing I do like and have done is use their pots and pans, kind of spendy, but they work nice. Since they work with a pot support that raises the bottom off the flame a bit it helps with controlling the heat. Great for frying fish cause full on you still don't over heat the oil.

That said I much prefer leaving the extra pots behind and just use the nice compact stove for coffee and boiling water. Fish can be done in the fire with some foil.
