Depending what you are looking to smoke and quantity you can go all big boy and go with a smokey oak bbq but that will set you back £5k plus.
Traeger are a good option if you want pellet smoker.
£5k is a bit steep. The other option is a Gozney Dome. There are Traeger and Weber pellet smokers all at a similar price.
