We've gone through many combinations of grills/stoves over the years. For the longest time we used, as already mentioned, the "good 'ol 2-burner Coleman." During that time we had a Weber gas Go Anywhere and then a Weber Q200. Now we are using another Weber gas Go Anywhere and a Coleman single burner plate thingie. This last change was made for better storage, lighter/easier setup and fact that it is mostly just wife and I camping now.
The Q200 was by far the best portable grill but they are heavy and the 200 version was bigger than we needed. Plus, my daughter wanted it for her new place...
