I have one of these Chauvet Bubble King units.Get one of these and put a small smoke machine behind it best option for heaps of bubbles
Chauvet DJ B-550 Professional Bubble Machine
Chauvets Atmospheric effects never seise to amaze with the B-550 Bubble King Professional Bubble Machine you can expect a massive Bubble output.djcity.com.au
It is a great machine, tones of bubbles. Always a hit for my church's Christmas in the park.
But there is better for the price.
At least your DJ City one is $270. Here in NZ, MDR lighting sells it for $400 ($380AUD).
I highly suggest a bubble machine that is plastic if you can. Metal machines like this rust.
(Don't worry, I got mine used for $20.)
