Just bought a smoke machine.

What did you get?
Since it's not a "critical tool", and I doubt I'll be using it all that much, I tried to find a fog machine at a "party store", but no joy there.

So I went cheap (Chinese?):

Got a 4 day weekend to play with it, and hopefully I can nail down this damn leak.
