The one your buddy in the next site is using.  He sets it up, usually cooks your food for you, cleans it and hauls it home.  Hee Hee! ;D

We have a 2-burner Camp Chef similar to this one.  We got it in the spring at Costco a couple of years back for something like $130.

Pros:

[li]Can be connected to our trailer's low-pressure quick disconnect with a separately purchased hose.  No need to bring separate tanks and we can use it near the back of our trailer instead of near the front.[/li]
[li]30K BTU per burner with big burners[/li]
[li]Can be used with its legs or on a (wood) table[/li]
[li]Using the legs, it's at a good cooking height for most people[/li]
[li]Big enough to use big pots or with their fry grill (highly recommended) or our 14" CI skillet to be able to camp for an army[/li]
[li]Cast iron and steel - can take some abuse[/li]
[li]Lots of available accessories (griddles, fry grill, BBQ box[/li]
[li]Quick to set up - just attach the legs, hose and windguard/backsplash and you're done[/li]

Cons:

[li]Fairly heavy (cast iron and steel, after all)[/li]
[li]Bigger than other 2-burner options[/li]
