I've been looking for a decent BBQ that folds for taking away but that's still a decent size. Most have flimsy legs and very thin steel but this one is superb quality. See the reviews.
I've not cooked with mine yet but I built it today and it's ten times better than the coleman one it's replacing. Chunky legs, thick steel, decent hinges. It's certainly heavier but that's a sign of quality.
