Have a look at the Kamado Joe
It's pretty much the same as a large BGE. For £760 you can get the cradle, heat deflector, pizza stone, extender grill, ash tool and cover.
I got mine in October and I'm well impressed. It's amazing how easy it is to hold the temp and how little fuel it uses.
If you buy a ceramic bbq you won't be disappointed even though they are quite pricey.
