For camping I’m more than happy with my $30 twin butane burners with the BBQ plate from our home BBQ, The plate fits nicely over these twin burner jobbies, so when I put the burner & plate into a large bag it compact and fairly light (as light as a BBQ plate can be)
When we want an oven, we pull out the foldable Colman oven and use that for Pizza, Nachos & Cakes. For meat use the camp oven in the fire.
Don’t get me wrong as I have used a Webber Q and it did cook a good meal. But for me personally, they just take up too much space.
