We use something similar but in ours we can fit a disposable BBQ into it. This makes the cleaning very simple. Just chuck the disposable part in the bin once it has cooled.
I got one very similar from B&Q last year and it's great you can fold it down into a suitcase kind of thing. One tip before putting the charcoal in the bbq cover the bottom with foil this makes cleaning up easier.
Thats exactly what i have and they are fantastic.
Easy to store, Easy to carry, folds down flat. and your not crouching over it because it's full size.
I had one of those for years and it was great. If you line the base with foil, as Matthew said, it is really easy to keep clean and it all packs into the case = even used to get the barbeque tools in mine.
The ebay item is more compact (i.e. the legs fit in the case), but is smaller then the B & Q BBQ. It is also more expensive than the B & Q one. On the other hand the B & Q BBQ is less compact, mainly because the legs are always attached to the base of the charcoal pan - it comes in quite a big box. The B & Q BBQ also has two or three scews/nuts protruding into the coals pan. If (like us) you line the bottom of the pan with foil before adding the coals (ideal for clearing up afterwards) you would need to be careful that the protuding screws/nuts do not puncture the foil lining.
In the end, we went for the B & Q BBQ because of the more generous cooking area. For those with less room, it would seriously be worth looking at the ebay item.
