Which is part of the reason I spent a few bucks more on a heavy cast iron grill from Lodge.
The other part of the reason is it has a cast iron grill which retains heat and browns my burgers better than the flimsy chromed steel grills on lesser models. You can also buy a cast iron stand for it to get it 3.5′ off the ground if you don’t want to just sit it on a table.
But this isn’t what Scott wants because he wants to do indirect heat as well and for that you need a bigger cooker with a lid. The "Portable Kitchen", which is cast aluminum (and therefore rust-free) rather than cast iron, is the closest thing in a larger cooker that I’ve seen.
You can always buy a cast-iron grill for a Weber. They’re available from a number of sources. The last place I saw one was in a Williams-Sonoma catalog, but I’ve also seen them at Toledo-based The Anderson’s General Store..
