We have a charcoal one, bought in the caribbean, Magma Marine Kettle. You can also get them with gas and they're jolly good.
Any really delicious recipes you have found? Yep! Clean your freshly caught mackerel in sea water, bone and squeeze on fresh lemon and lime juice, give a hour and throw on BBQ...delicious!
Having been a user of disposables for the last 3 years on/in a frame I aquired said Cobb a month ago and have used it over a dozen times since both on land and sea. OK it's takes 5 mins to clean it (the next day) but so what. Food cooks brilliantly and literally everything ends up eaten due to a lack of charcol etc etc. The cheaper one in the earlier thread doesn't have the teflon coated grid but you can use a metal scourer on it without making a mark!
