This BBQ is smallest kettle Weber do. (Not including the Smokey Joe). The 47cm is better suited for a couple of people and if it is the compact version then you will find its best used for steaks, chicken fillets & sausages.
Weber 57cm Kettle
The 57cm is my model and is called the Original. They do do this in the compact version like the 47cm but again the compact is better suited to grilling rather than roasting. If you get the original or premium then you will have no troubles roast on these.
Weber 67cm Kettle
Now this is pretty big kettle and you will be cooking for party's with this. You can get around 3/4 Beer Can Chicken's on here so its a pretty serious BBQ.
Dancook 1600
This is the
45cm Diameter stainless steel kettle and has a different way of getting the air to the coals. The patented liner in Dancook causes the combustion air to pre-heat so the cooking effect is encreased by 50%
Leisuregrow is one of them BBQ brands that is not cheap but not top range in my eyes. This is small cook area but deepish bowl so still a good cooking BBQ. This even has a 10 year warranty which is good. Only thing I don't like about Leisuregrow is they have got into their heads that this Grillstream Technology is the way forward, sorry but its not and it takes away the whole BBQ experience.
Outback Cook Dome 702
Outback is not a brand of BBQ for me, they advertise like they are making the best you can get when they are far from it. This kettle will do the job, it's basic but straight forward but over priced at the same time. It only has a 1 year warranty too so you want to keep it covered and don't scratch that paint because I can bet your life it will rust quick.
