Many years ago, I was having a party and decided to make fondue. A friend of mine had recently quit drinking, and I wanted to support her, so decided that in place of using wine and kirsch, I would use yogurt.
There were 2 Swiss and 2 Germans at the party. Who were appalled! One of those people has been my friend for 35+ years and still complains about that fondue!
Nowadays I have a stand for a cheap fondue set, but have thrown out the other parts. I use an ordinary saucepan on top of it, a restaurant sterno set, and some decent long forks.
