It depends what type you’d like. Pro Q do an excellent range in bullet smokers for sensible money. They have very good build quality and a good after sales service. They’re a modular design, so have the ability to expand if you need a little more cooking space. Ceramic grills are very good on fuel and again, come in a variety of sizes. The Aldi/Lidl ones are very good for the money, with something like the Kamado Joe being more at the top end quality wise, but at a cost. All of the above are fairly easy to use and once setup to smoke, don’t need too much attention. Unless made of very heavy steel, avoid an offset as they’re difficult to use, especially if small and very labour intensive. That said, they give the best smoke flavour by far as they’re solely wood fired.
