I had a look at the website - the Davy Crockett looks quite nice, albeit small - but an attractive price point (albeit there does appear to be a treasure-island premium compared to the US price - even taking VAT into account).
As someone who just cooks for friends and family (no competition) pork ribs are easy - just start them in the morning and they are ready for lunch - potentially even Beef ribs if I get an early start. Brisket and Pork butt - that's another story - it could potentially mean starting in the early hours of the morning - and tending the fire to make sure it doesn't go out overnight. Lots of stress. So in theory could do these in the Davy Crockett - and the rest in a pro-q or other.
Anyone used a davy crockett? Of course if it works as well as people are saying - I may well regret the purchase of this smaller grill
