There are some Youtube videos out there too -- just search DIY Smoke Machine. Mine worked great to help me find a blown o-ring on an intake sensor on my BMW E36. The leak occurred on the bottom side of the intake tract and no amount of ether would have helped me find that one!

I'm with Strawman. Build your own off the web. I'm too cheap or lazy use the glow plug or glycerin. I used a match and a rag soaked in WD-40. Works like a dream. Used it once to diagnosis leaks on 4.0 Ford and 2.7T Audi. I think I'm into mine $25.

Ive used propane from my bbq tank. It kills the engine. Just try spraying some down the air intake and it dies immediately. Figure out a hose attachment to the propane tank so you can spray it on suspected areas. You will also need a long hose to hook to your air intake so it will pick up fresh air somewhere else.
