Great site you all have here!

I've owned a Kelly Kettle for about a year now.
I am impressed with the quick boiling time, and miniscule amount of fuel required.

I bought mine at Water Strider:

If you scroll down you'll see the kettles.
But what I want to recommend are these items to compliment the KK(a bit further down from the kettle):

1. Kelly Kettle pot holder.
This device sits atop the chimney and works well for cooking in a small pot whilst boiling your water.

2. Folding water bucket.
A great way to transport water, and store the KK when not in use (just be sure to let it cool-off first!) I also store a dozen or so sticks of cedar kindling along side the KK. That way I can always be sure of having dry fuel. (2 sticks of cedar kindling will boil a kettle full of water!) I also throw in a few homemade sawdust-candle wax-egg carton firestarters.

3. Insulated plastic cup system.
Works great for cooking dehydrated foods and having a hot bev.
