I scored a brand new, complete and unused Kelly Kettle for $4 from the Salvation Army today.
Kelly Kettles are a marvel of thermodynamics. Instead of lighting a fire under them, you light the fire inside the double-walled boiler. The tapered walls make the fire draw something fierce, and you get boiling water in a very few minutes. I kippered myself a bit making the morning coffee, but it was worth the effort.
