I have found the simmer control on the #1 burner (the burner with the generator over it) on Coleman stoves to be excellent. Nearly as good as the gas stove at home. #2 burner is less controllable. Still, you can't beat the quality per dollar even of a newer dual fuel.
The real jewels out there are the late 50s-mid 80s stoves. There are piles of them every week on Craigslist and will work for decades with minimal effort. All parts are still available and they can be field serviced with a few simple tools. It's the best $20 you will ever spend on camp gear. There is a 1 day learning curve when using them. After that, lighting, relighting, simmering etc are all a breeze. And no bulky propane tanks.
