Don't know about .se but they're really cheap in the US now. All the
department stores have them for Halloween at $30 a pop. I paid $200 for one
to use with my lasers six years earlier. The fog juice is cheap, too.

I assume you need "dry" fog. You can make lots of "wet" fog with an
ultrasonic fogger. They use those in Halloween decorations now as well.
I've seen them for sale in the water fountain supplies at big craft stores
like Michaels--I think they were about $40.

Even simpler--hydrochloric acid (look for muriatic acid at the hardware
store) in proximity to any ammonia-based cleanser. The more ammonia content
the better. Copious clouds of ammonium chloride fog will be yours.

What, you don't mix your own model airplane fuel?

Don't forget the lasers...
