Years ago, I bought a $20-$30 Walmart grill that uses the small bottles. That thing was cheap and chincy and lasted for years. I bought another one that sucked (same product but different quality). Bought a red Coleman unit with a single burner and griddle plate. It sucked too. I do have a more standard Coleman 2-burner stove which is excellent...but it's just a stove.
Went on a quest a while back to find a great grill. Looked at everything, read about a million reviews, even nearly purchased some of those listed in this thread. At the end of the day, I ended up with a Camp Chef Explorer Series 2-burner with grill box. It takes up more room than the other styles, but it's worth it. Takes me about 2 minutes to setup/takedown. Our use of this has inspired others to follow suit. It's simply wonderful.
