We're in the same boat, always on a tight budget and looking for
bargains. We live in Northern California and a few years ago we found
a kama at a local import shop that was made in China. My husband gave
it to me as a gift -- he wouldn't tell me the exact cost, but knowing
our budget I know it could not have been very expensive! We often use
an electric hot plate for demonstrations, with tetsubin or other small
kettle.
I'm curious to know your solution, please post updates!
