The paint can smoker is a simple coil of nichrome wire wrapped around a wick that is soaked with mineral oil. Others use a GM glow plug as the heat source. Then use a common low pressure BBQ gas regulator to drop the air/nitrogen pressure down to about.75 psi. The entire thing is built using a metal paint can.
In operation they work just like the expensive ones but without all the extras like switches/lights/flow meters (you could easily build those in if you wanted to but for a simple smoke generator they are not needed). Connect to the vehicle battery and wait thirty to forty five seconds for them to create smoke. Connect the hose to the test port or whatever you are testing, hook up the air to "push" the smoke through the system.
Price wise it depends, there are DIY builds all over the internet, plus folks sell them on eBay.
I used one for a while and it did the same job as the "store bought" versions I have now. However 99% of them use the same type of parts inside as the paint can units, just in a nicer case with the lights and switches to make them easier to use.
Price wise it depends on if you build or buy. I had maybe $30.00 in mine.
