Denice, we purchased a Kamado, not the Big Green Egg brand, second hand, in 1968...
from a Marine who had purchased it in Japan and got tired of moving it around. I almost weep when I remember the taste of chicken or ribs cooked on it. There is nothing more delicious! We became Kamado-less when I backed into it in my carport in 1974, and it shattered into a dozen pieces. I've kind of lost my enthusiasm for outdoor grilling, (got tired of smelling like smoke), and DH isn't a chef, so we don't use one any more. Ours was red, not green. But if you want the finest-tasting grilled food you'll ever put in your mouth, buy one!
Do a Google search for "Kamado", and you might find some other sources. Maybe even find a used one for sale on e-Bay?
