I've been thinking about using a smoke machine for tricky emissions problems, but i cant justify upwards of £500 for something i would only use twice a year.
My thought is why not use a smoke machine that is designed for discos ,available from aroud £30?
Apart from the fact i would have to stop my hips swivelling and my feet tapping whilst using it, the only disadvantage i can think of is connections and controllability.
Anyone else tried/thought about this?

Cheers

Colin.
