Another source for the Kelly Kettles in the U.S. is Garrett Wade (www.garrettwade.com).

Very comparable to what Lee Valley has (in their general stock). They charge a few dollars more, but available with the large Kelly Kettle (they call them "Foul Weather Kettles") is an accessory kit.

Quoting their site now: comprised of a small 5-1/2" diameter fry pan, a fire grate/grill, a deeper Cooking Pot, plus a Handle) can be used with the Base of the Large Kettle.

That might be a nice add-on to go with a Kelly Kettle, don't know how it compares functionally to the Thermette's advertised ability to cook with or without the water boiling on the base.
