The Weber Q-series gas barbecues are the simplest Weber gas barbecues. These barbecues only have 1 gas burner and not a lot of extra options. The Q1200 is the smallest model and the Q2200 the largest. Both Weber Q BBQs come with and without an underframe. Choose a Weber Q BBQ with underframe if you want to grill at a comfortable height. Don't have a lot of space? Get a Q-series BBQ without an underframe so you can easily place it on the garden table.
