We have the Weber Q 1200, bought it a few weeks ago and have used it many times. We bought it for the camper and the house.
It is a little big. We have to remove the top half and store it separately from the bottom half. Not really a big deal for us, since we usually take longer trips. In the summer, we are in once campground for 4 months.
I've used several portable propane grills and the Weber Q is very easy on the propane. I can get 4 meals out of 1, 1 lb canister. I have it connected to a 20 lb tank now, but used the 1 lbers for the first week or two of use.
I am happy with the purchase. I was a little reluctant because of the size and the price, but after going through the cheaper models quicker than I expected, I think I made the right choice. Weber makes a quality grill.
