Like DS my top fell off and broke a week ago. I called Atlanta and was informed the cost of a new large top was $99.00 plus shipping. My dealer (Hearth & Home, Hampton Falls N.H.) sold me one at cost $70.00. They told me that probably someone had tried to close the dome without using the auto-lock and that pulled the dome out of the band. The next time it was lifted the dome crashed. I did not get silicone with my egg, but I did glue the new dome in with high temp silicone frome Rutland.
