Oh. The company has gone out of business.
I spent some time looking at other grills on line. I am not fond of the basic Weber kettle, but it looks like the vast majority of barrel grills leak air like a sieve, so you can't damp down the fire.
And I do not want a gas grill.
This is going to be a problem. Possibly a problem solved with a Weber kettle, but still a problem. *sigh*
