I recently picked up a 1966 Sazco Kamado. It's the first kamado to be granted a US patent. It was stored in a barn for 25+ years and is in excellent condition. I polished the aluminum lower damper door, replaced the cracked ceramic top damper with a Kamado Joe daisy wheel, replaced gasket, and patched a few minor cracks in the fire box. I also drilled a holle for the thermometer, talk about being nervous! It works great and you'd never know it was 45 years old.
Here is a brisket on it a month or so ago.
Its grate is 18" and all together it weighs about 170lb.
