I have one for camping from B&Q that you might want to consider. Its only £17 and lastest me a couple of years already. Its a similar size with detachable legs.
Looks nice but its still the gas barbie for me. Cant be bothered with the messing around charcoal entails. I also like to take time over barbies instead of having a short window when charcoal is ready to cook food on. Gas barbies are more versatile as they can be turned on and off as required. Before every one shouts about charcoal imparting flavour to the food just consider why charcoal is used. Its inert having all the volatile elements driven out during the initial burning. Its the juices from the food dropping onto the hot coals during cooking that produce the smell. There fore thats why in blind tastings people cant tell if food has been cooked on a gas or charcoal barbie.
