Aloha, Tattrat:
You can deal with the smaller size easily by doing a double decker. Never had the need since I only cook for two regularly, but never had a problem with big crowds. A 20 pound turkey, two or three chickens, an eight pound prime rib, a huge ham, none caused me any grief.
The price for the unit is high, but is cheap in the long run since it will last 50 years or more.
Indirect grilling works perfectly, pizzas turn out fab, smoking is easy. Tonight we had hungarian sausages and grilled zuccini.
One of our considerations was the fact that a 20 pound bad of (BGE) charcoal lasts for months. I have several in reserve since bad weather can knock out our electricity for many days on this small island. You cannot refill propane tanks without elictricity.
Who's the cute kid on your picture?
Aloha from paradise, Hartwin
